Thomson currently has two account systems - one for the website and CAD model downloads, and one for e-commerce. We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:
Shaft support blocks are used for end or intermittent support where loads are light and slight shaft deflection is not a concern. Unlike shaft support rails, blocks do not permit longitudinal passage of open-type ball bushing bearings. Shaft support blocks enable clamping of shafts, type SB and eliminate the need for bolts to maintain shaft position. Shimming is suggested for high precision applications to eliminate the effect of variations in surface of base or manufacturing tolerances between supports.
Type SB shaft support blocks enable clamping of shafts and eliminate the need for bolts, etc. to maintain shaft position
Type ASB shaft blocks, manufactured from high strength extruded aluminum, provide either end or intemittent support in applications where loads are designed with a regerence edge on one side of the base
Type FSB flanged support blocks offere perpendicular mounting without the need for special adaptor brackets
Shaft Rail Assemblies are for use with OPEN bearings. Delivered with the shaft and rail pre-assembled.
Low Profile (LSRA) - Low profile rail design
Standard Profile (SR) - Standard profile rail, aluminum alloy rail
Extra Rigid (XSRA) - Extra Rigid, Ductile Iron rail
The Nominal Shaft diameter. The actual diameter will depend on shaft tolerance chosen. See the individual product detail page for the actual diameter upper and lower limits.
AL - Aluminum Shafting
L - For use with Super, Super Smart and XA Open and Adjustable Ball Bushing Bearings and Pillow Blocks
S - For use with A type ball bushings
N - For use with needle roller Bearings
D - For use with Thomson Die Set Ball Bushing Bearings
G - Grooved shaft for use with Thomson Ball Groove Ball Bushing Pillow Blocks
XL - For use with XR bearing (Carbon Steel)
The material of the shaft (where the ball bushing travels). In the case of a shaft rail assembly the shaft support may be a different material. See the individual product detail page for the shaft support material.
Standard - Standard shafting. Typically used with closed bearings and end supports.
Predrilled - Mounting holes are Predrilled through the shaft or assembly.
Shafts - Predrilled shafts are designed for use with Open bearings where the customer is assembling or using a custom support. Consider utilizing a Shaft Rail Assembly instead.
Shaft Rail Assemblies - Predrilled mounting holes are for securing the assembly to the mounting surface.
Deep Case - where the case depth is two times the normal depth
