STANDARD COMBINED ROLLER BEARINGS
Originally used in fork trucks, combined roller bearings (or combi bearings / combined bearings) can be used in a variety of horizontal, vertical, cantilevered or telescopic linear motion applications.
Bearings are available from stock in standard, adjustable & Jumbo ranges. Each bearing has a corresponding steel section (channel) and is available with mounting plate for ease of assembly. Calculate which size you need using Hertzian Pressure.
Read our technical information on Combined Roller Bearings or view our application examples. When corrosion resistance is required, the bearings and mounting plates can be supplied with Thin Dense Chromium (TDC) Coating.

All dimensions are in mm and loads are in kN.
Note: All lube points are for M6 grease nipples (not supplied).
4.053 & 4.054 do not have grease holes.
LOAD CAPACITIES
Static and Dynamic Load Capacities for radial and axial rollers. If used with mating steel profile, the limiting load is the Hertzian Pressure.
