Roller Pillow Block Advantage

Roller Pillow Block

Roller Pillow Blocks from PBC Linear have several advantages over profile rails.
vs

Profile Rail Technology

Profile rails are superior for high precision applications.

Roller Pillow Block

  • Superior for joined rail applications
  • Low coefficient of friction ideal for heavy load transport applications
  • Best suited for horizontal applications with normal downward loading
  • Cam followers can be utilized for high speed applications up to 25 feet per second
Key features of a roller pillow block from PBC Linear which make them ideal for high load and joined rail applications.
  1. V-block shaped support rail design aligns shaft centerlines simplifying joined rail assemblies
  2. Support rail mounts using standard fasteners
  3. Floating pillow block option available absorbing up to 0.125" out-of-parallelism reducing installation time and cost dramatically
  4. Simple eccentric bearing adjustment allows tailored bearing fit to application requirements

Reliability

  • Large cam follower design delivers superior contaminant resistance
  • Excels in long travel applications requiring joined shafts or rail assemblies
  • Accessories such as lubrication ports and scrapers available for ease of maintenance and maximum life

Profile Rail Technology

  • Superior for high precision applications
  • Proper installation requires machining and detailed alignment procedures as highlighted below
Profile rails are costly to install and require high precision when joining shafts.
  • Manufacturer guidelines require a machined mounting surface and datum plane that can be extremely expensive or impractical in long rail lengths
  • Factory-matched rails must be specified when joining guides to ensure precise alignment of running surfaces, adding expense and time
  • Precision tapped mounting holes are required
  • Specified torque sequencing is needed to avoid rail distortion

Accessories

Accessories & Options

To increase the performance of Roller Pillow Blocks the following options are offered.

Top Grease Option

Roller Pillow Block rollers are lubricated and sealed. In some applications it is desired to re-grease the main support roller. The top grease option can help achieve full bearing life in applications that reduce or contaminate the grease of the roller. Such conditions may exist in applications where solvents or contaminants leach out the grease through the vents in the seals, or where contaminants are so fine or extreme they must be purged out of the roller with fresh grease. The top grease option is also recommended when high speeds or high temperatures are present. The top grease option is available on pillow blocks that are 1-1/4" or larger. To order, add the suffix, “TG” after the pillow block model number.

Note: Shock, vibration, and moments may affect the life of the pillow block.

Top grease option for Roller Pillow Blocks for PBC Linear designed to help achieve full bearing life in applications that reduce or contaminate the grease of the roller.

Floating Option

The only product on the market that addresses the non-parallel shafting problem is a Roller Pillow Block with the floating option. Also useful when trying to align long shafts, floating Roller Pillow Blocks should be used on one shaft with the standard pillow block on the other. Special grease is included for the grooves on top of each floating pillow block. During installation do not over-tighten the mounting bushings as this will cause them to bind. To order, add the prefix, “F-“ to the single, double, or twin Roller Pillow Block number.

Scraper Option

the top of the Roller Pillow Block shaft with the scraper option. Available only on specially machined pillow blocks, the scraper is mounted to each end of the bearing assembly to clean the shaft in either direction. Made from spring-tempered beryllium copper that conforms to the shaft diameter, the scraper will perform successfully after a short break in period. Scraper model is not available as a retrofit. To order this option, add the suffix “-S” after the pillow block model number.

Scraper accessory for Roller Pillow Blocks from PBC Linear are designed to reduce dirt accumulation on top of the Roller Pillow Block shaft.

Linear Carriage Lock

The linear carriage lock is a positive locking device for linear slides, carriages, and bearings.

The locks are:

  • Self-centering
  • Corrosion resistant
  • Strong holding
  • Contaminant resistant
  • Easily mounted
  • Maintenance-free

Pillow Block Rebuild Kits

The Roller Pillow Block rebuild kit contains all the parts required for a complete unit rebuild:

  • One fixed side roller
  • One eccentric side roller
  • One top support roller
  • One top roller axle
  • One set screw

To rebuild a Double or Twin Roller Pillow Block, please order 2 kits.

All parts of a Roller Pillow Block should be replaced before re-installation.

Technical Information

Orientation & Cantilever Loads

When a linear motion system is subjected to a cantilever load or moment, the system designer must take into consideration these type of loads will greatly affect the performance of the system. Roller Pillow Blocks are not suitable for these types of applications because the moments will load the side rollers and cause premature failure. If the moments or cantilever loads are minor, loads may be acceptable. For this reason we ask that you consult the factory.

Normal Loading for Roller Pillow Blocks from PBC Linear is when the Roller Pillow Block is upright and the load is oriented downward.
Roller Pillow Blocks from PBC Linear are not suited for intverted loads.
Consult PBC Linear before using Roller Pillow Blocks with a cantilever load.
Consult PBC Linear before using Roller Pillow Blocks in a vertical orientation.
Chart used to select the correct Roller Pillow Block from PBC Linear by showing the relation between travel and load.

Determining Pillow Block Size & Model

To determine the proper size Roller Pillow Block for an application, refer to the chart using the worst-case load and the required travel life. Select the Roller Pillow Block above where the lines intersect. This should be suitable for anticipated travel life and loading.

Note: Shock, vibration, and moments may affect the life of the pillow block.

Note: Chart is rated at 10% accuracy. Figures are based on a safety factor of one.

Adjustments

Roller Pillow Blocks are factory set for Simplicity® 60 Plus® shafting. Adjustments can be made to the eccentric cam follower to either increase or decrease the shaft clearance.

Located on the same side of the Roller Pillow Block as the set screw, the eccentric cam follower is adjusted by using a stubby allen wrench while allowing a 0.002" feeler gauge to freely move between the shaft and the eccentric roller. The fixed side must remain in contact with the shaft. If care is taken not to overload the roller, then a slight pre-load is possible. Rollers should never be tightened to the point where they cannot move freely.

Roller pillow blocks from PBC Linear have an adjustable eccentric cam follower, allowing for precise modifications to increase or decrease shaft clearance.

Turning a Curve

A single Roller Pillow Block has the ability to turn a curve or run on a non-linear system. The following table lists the minimum track radius that the single Roller Pillow Block can tolerate without additional alteration.

Single Roller Pillow Block from PBC Linear are designed to navigate curves or operate within a non-linear system.

86"
1012"
1214"
1618"
2036"
2440"
3244"
4852"

Lubrication, Rails & Bearings

The rollers are internally lubricated for life, but the rails must always have a layer of grease. As a guideline, reapply fresh grease every 50,000 cycles.
