When a machine has to carry heavy radial loads at speed, a cylindrical roller bearing is often the right answer. The rollers run parallel to the raceways, so contact happens along a line rather than at a point, which spreads the load across a broad surface. That gives the arrangement stiffness and staying power in rotating equipment. RKB supplies this type for gearboxes, pumps, fans and process machinery that runs continuously, where precision and resistance to fatigue matter.

Reading the reference is the first step. A basic number is paired with a suffix that points to an internal design variant, so 314385 GB2 is a cylindrical roller bearing built to a particular cage and tolerance configuration. The GB2 suffix generally signals a defined execution, for instance a set internal clearance or a treated raceway surface. If you need the exact characteristics of the GB series execution, pass the full part number to our team.

These bearings turn up in speed reducers, machine tools, mining equipment, steel and cement operations, and also in large centrifugal pumps, industrial fans and heavily loaded conveyors. Their capacity for radial loads and moderate shock makes them a fit for tough surroundings where dependable running and long service are the goal.

Selection comes down to the radial load, the speed and the conditions on site. Check which cage is fitted, what internal clearance is specified and whether sealing is needed given how contaminated the environment is. At installation, line up shaft and housing accurately and use the lubrication called for by the manufacturer. Getting those details right is what keeps a bearing from failing early.

Standard boundary dimensions mean cylindrical roller bearings can be matched across brands. If you are replacing a part from another maker, compare the main dimensions and the type of execution. We can help you find the RKB reference that corresponds to the part you are running now, while keeping the original performance. Tolerances and internal clearance are worth confirming before you swap anything.
