# Why Maintenance Teams Specify HKR29D for Heavy Radial Loads

Line contact between rollers and raceways gives a cylindrical roller a high radial capacity compared with a same-size ball bearing. That is the usual reason a maintenance team writes HKR29D onto a pump or gearbox bill of materials.

The design is separated, which helps when the inner ring is an interference fit on the shaft and the outer ring stays in the housing. It is not a self-aligning bearing, so housing alignment and shaft deflection still have to stay inside good practice.

Review the HKR29D bearing listing for application notes and stock. TFL Bearing can discuss OEM or neutral packing if the part is going into a motor rebuild kit rather than a branded box.
