Full-complement cylindrical rollers. No cage — maximum number of rolling elements in a compact envelope for high radial load capacity.
Flange rings for axial guidance. Separate flange rings locate the rollers axially in yoke-type and track-guided arrangements.
Labyrinth seals. Sheet-metal angle-ring seals on both sides retain grease and resist contamination at low speeds.
Lubrication hole in inner ring. Allows relubrication through the inner ring when mounted on a shaft with a grease passage.
Conveyor track guidance rollers
Cam drives and cam tracks
Material handling and lifting equipment
Industrial machinery track rollers
NUTR50-X is a commonly used support roller designation. Several manufacturers list similar part numbers in their catalogues. Because suffix letters and seal/outer-ring variants can differ between suppliers, we recommend confirming the exact suffix on your original bearing before ordering.
If you are replacing an existing bearing, send us the original part number or a photo of the bearing — we will check whether the dimensions and configuration match before you place an order.
