(92) The MR43 Series Heavy Duty Linear Bearing Rail is the largest size rail in the MR family measuring 43mm across the back. These rails are made of hardened, cold drawn carbon steel that is treated with the innovative T RACE NOX® process to make them highly corrosion resistant. When combined with R Series Sliders and Rollers, they create a high performance linear bearing system that is durable in even the harshest of applications and environments.
9720 N (2185 lbs) capacity per 5 roller slider or 7200 N (1619 lbs) capacity per 3 roller slider
43mm x 37mm assembly cross-section
Rail lengths up to 4000mm (157 in) with splicing for longer lengths available
Convex running surfaces to shed contaminates and water, ...
(6) R Series Roller Sliders for MR43 Series Heavy Duty Rails are made from Zinc plated Steel with integrated end seals, side seals, and auto lube system. The Sliders are supplied with either 3 or 5 rollers for radial load capacities from 7200 N (1619 lbs) up to 9720 N (2185 lbs).
(8) R Series Rollers for MR43 Series Rails are heavy duty double row ball bearing rollers made from 52100 Bearing Steel or 440C Stainless Steel. The rollers are lubed for life and sealed with 2RS side seals. The rollers can be used to construct custom sliders for use in MR43 Series Rails or with FXR43 Rails. The Rollers have radial load capacities of 3600 N (809 lbs) per roller.
(2) VF Series Fasteners are used to attach MR Series rails to a mounting surface. VFL fasteners are a special low head TORX fastener for the MRL rails. VFS fasteners are metric, flat head, cap screws for the MRS rails.
