Strong Line of Gear Racks utilize carburized case-hardening process to optimize strength of rack, including tooth flanks and root, mounting holes, and back and side surfaces. This allows back surface to be used with cam follower roller bearings for guiding axis. Racks are precision ground on teeth and all sides to achieve accurate pitch deviation and parallelism. With max holding force, mounting holes insure rack remains stationary under high forces.

• They run quieter than the straight, especially at high speeds
• They have a higher contact ratio (the number of effective teeth engaged) than straight, which increases the load carrying capacity
• Their lengths are nice round numbers, e.g. 500.0 mm and 1,000.0 mm, for easy integration with machine bed lengths; Straight racks lengths are always a multiple of pi., e.g. 502.65 mm and 1005.31 mm.
• In most cases, they cost the same as the straight racks!
