Linear bearings from PBC Linear include plain linear bearings for maintenance-free, self-lubricating motion, linear ball bearings for high-speed, low-friction performance, and cam roller pillow blocks for heavy-load, long-travel durability along round or square shafts or profiled rails. Simplicity® plain linear bearings use FrelonGold® PTFE liners to deliver consistent low-friction operation in harsh environments, including extreme heat, dirt, debris, and vibration. Round shaft plain bearings support rotary, linear, and oscillating motion, while square shaft versions support linear and oscillating motion only. They are available in standard, twin-size, flanged, and pillow block designs, including thin-walled, sleeve bushing, and die set variants. Linear ball bearings feature a heat-treated outer ring, quiet resin retainer, and recirculating steel balls to enable higher speeds and eliminate the 2:1 binding limitation of plain bearings in cantilevered applications. They are available in standard, twin-sized, flanged, and pillow block housings. Cam roller pillow blocks use open housing designs with single, double, or twin sets of coated steel cam rollers for heavy-duty performance along rail-supported round shafts. All linear bearings match standard shaft sizes in inch, metric, and JIS.

Frequently Asked Questions
What is the difference between plain linear bearings and linear ball bearings?
Plain linear bearings use self-lubricating liners and are ideal for harsh environments, while linear ball bearings use recirculating steel balls for low friction and higher-speed performance.
What are the benefits of plain linear bearings?
Plain linear bearings provide maintenance-free, self-lubricating operation and perform well in environments with heat, dirt, debris, and vibration.
What are the advantages of linear ball bearings?
Linear ball bearings deliver high-speed, low-friction performance and eliminate the 2:1 binding limitation of plain bearings in cantilevered applications.
Which linear bearing is best for dirty or harsh environments?
Plain linear bearings are best suited for dirty or harsh environments because their self-lubricating liners resist contamination from dust, debris, and moisture.
Which linear bearing is best for high-speed applications?
Linear ball bearings are ideal for high-speed applications due to their low coefficient of friction and recirculating ball design.
When should cam roller pillow blocks be used?
Cam roller pillow blocks are ideal for heavy-load, long-travel applications, using coated steel cam rollers in open housing designs for durable performance along rail-supported round shafts.
Do linear ball bearings require lubrication?
Yes, most linear ball bearings require lubrication for optimal performance and service life, unlike self-lubricating plain bearings.
What motions do plain linear bearings support?
Round shaft plain bearings support rotary, linear, and oscillating motion, while square shaft versions support linear and oscillating motion only.
Are linear bearings interchangeable with industry standards?
Yes, most linear bearings are dimensionally interchangeable with industry-standard sizes.
What sizes are available for linear bearings?
Linear bearings match standard shaft sizes and are available in inch, metric, and JIS sizing.
