Round Shafting & Bearings

Lintech’s Round Shaft Linear Bearings product family consists of Precision Linear Shafting, shaft supports, shaft blocks, round shaft assemblies, round shaft linear bearings, super ball bushings, pillow blocks and carriage assemblies. The cut-to-length, 1060 case hardened steel precision linear shafting is available in both Inch and Metric diameters with different Class tolerances. Class L, Class S, and Class N shafting is available.  

Shaft assemblies are provided in single and dual rail versions, with diameters from 0.5 inch (12 mm) to 2.0 inch (50 mm) and lengths to 192 inches (4800 mm).   Open and closed linear bearings & pillow blocks are provided in both inch and metric sizes.   The single shaft assemblies (SA series), along with linear bearings (SLBO & DLBO), are typically used when the mechanical designers wish to spread apart the SA series and make their own custom carriage assembly.   

The dual shaft assemblies (TRSA series) and carriage assemblies (TRCA series) are utilized when ease of installation is of essence.   The pre-aligned shafts on the TRSA series and the pre-aligned linear bearings on the TRCA series allow the user to quickly mount the components in their system.

Lintech’s family of cost-effective short-delivery Round Shaft Linear Bearing products includes:


Shafting - Inch and Metric - Lintech’s precision "cut to length" 1060 carbon steel inch and metric shafting is manufactured with the highest standards for surface finish, surface hardening, roundness and straightness.  These manufacturing procedures provide a quality shaft with long life and optimum performance in today’s demanding applications.  Inch diameters are available from 0.25 to 2.0 inches in class L, S and N diameter tolerances.  Metric diameters are available from 8 to 50 mm.  Any length is available within .001 inch increments, up to the standard maximum stocked length.

Shaft Assemblies

SA Shaft Assemblies - Lintech’s single Shaft Assembly (SA series) is a complete assembly which simplifies the use of a linear bearing in a mechanical positioning application.  Each assembly has a steel shaft mounted to a black anodized, precision machined, aluminum support.  The pre-drilled base mounting holes in the 6, 12, 18, and 24 inch supports allow for easy customer mounting.  The SA assemblies come in standard lengths from 6 to 192 inches, and with shaft diameters from 0.50 to 2.00 inches. 

TRSA Shaft Assemblies - Lintech’s TWIN RAIL® Shaft Assembly (TRSA series) is a complete assembly which simplifies the use of a linear bearing in a mechanical positioning application.  Two steel shafts are mounted and aligned on the common base, therefore eliminating the alignment process required for two separate shafts.  The pre-drilled base mounting holes in the support allow for easy customer mounting.  Each 6, 12, 18, and 24 inch aluminum support has two threaded holes at one end to assist in leveling the assembly.  The TRSA comes in standard lengths from 6 to 192 inches, and with shaft diameters from 0.50 to 2.00 inches.

Round Rail Linear Bearings

LBCA & LBOA Precision Linear Bearings - Lintech’s LBCA & LBOA offer an "all steel" linear bearing design.  This provides for operation in high temperature environments (up to + 600o F) and can offer a smoother operation when compared to the LBC & LBO style bearings for some applications.

LBC, LBO & Metric Linear Bearings - Lintech’s high capacity linear bearings have a ball conforming outer race coupled with a self-aligning feature which allows for zero bearing clearance while maintaining smooth operation.  The independently self-aligning outer bearing races insure smooth operation by allowing miss-alignment up to ½ degree in all directions.  These linear bearings are available in "open" or "closed" styles.  The closed style is available in 0.25 to 2.00 inch nominal diameters, while the open style is available in 0.50 to 2.00 inch nominal diameters.  Metric diameter bearings are available from 16 mm to 50 mm.

Pillow Blocks

SLBO, SLBC, DLBC & DLBO Pillow Blocks - Lintech’s SLBC and SLBO series have one linear bearing and two wiper seals per pillow block, and are self-aligning in all directions.  The SLBO and DLBO series have a screw for pre-load adjustment to reduce the shaft and bearing clearance.  Lintech’s DLBC and DLBO series have two linear bearings in one aluminum pillow block, separated by a wick that serves as an oil reservoir.  Each pillow block housing provides a flat top surface for load mounting and alignment.

TRCA Carriage Assemblies

TRCA Carriage Assemblies - Lintech’s TRCA series, TWIN RAIL® carriage assemblies are pre-engineered assemblies which have either SLBO or DLBO pillow blocks mounted to a 6061-T6 aluminum, black anodized machined plate.  The pillow blocks are pre-aligned and doweled to the carriage plate to match Lintech’s TRSA series shaft assemblies.  The use of a TRCA carriage assembly and a TRSA shaft assembly reduces the process of mounting and aligning two shafts and pillow blocks.  Each carriage surface is machined which allows for accurate mounting of customer loads, and are available with mounting holes with stainless steel inserts.  Carriage assemblies are provided with pillow blocks for shaft diameters from 0.50 to 2.00 inches, and come in lengths from 6 to 30 inches.
