The XGGE KRRB series covers SKF Y-bearings, a design made to sit inside a housing while gripping a rotating shaft at moderate speed. Its inner ring reaches beyond the bearing width and carries set screws, so it can be locked directly onto a commercial shaft. The outer ring is spherical and seats in a matching housing bore.
Reading the code is the fastest way to identify a unit. Take XGGE20KRRB, XGGE25KRRB or XGGE30KRRB: the digits stand for the shaft size the bore is machined for, so a larger figure means a larger shaft. The letters after the digits describe the seal arrangement and the way the unit grips the shaft. Because the inner ring is extended, no special shaft preparation is needed for mounting.
Typical installations are belt conveyors, packaging lines, bucket elevators, mixers, blowers and power transmission equipment. Food, chemical and aggregate plants rely on this design, as do agricultural machinery and water treatment systems. Where dust, moisture or routine washdowns are present, the seal keeps contaminants away from the raceways, provided the housing and shaft suit this mounting style.
Selection starts with two items: the shaft diameter and the housing the unit will sit in. The KRRB seal holds grease in and keeps dust and water out; for pressure washdowns, consider extra protection. When mounting, press the bearing into the housing without hammering the outer ring, tighten the set screws against the shaft, and confirm alignment before running. Grease from the factory covers start-up, and afterward the lubricant condition should be reviewed for the application.
Interchange between brands is usually done by shaft number and locking method, yet tolerances and sealing vary from one series to another. Before fitting another manufacturer's unit, check the bore, the inner ring width, the set screw style and the outer ring geometry; an existing housing may only accept a bearing with the same outer shape. Our team can review the equivalence for you.
Send the bearing code by WhatsApp along with a photo of the housing and the measured shaft. That information lets us confirm the XGGE KRRB variant and prepare your quote. Split plummer block housings, bushings and lubricants can be included to complete the assembly.

Frequently asked questions
- What does the KRRB suffix indicate on the XGGE series?
- It covers the sealing arrangement and the shaft locking method. On this series the inner ring is extended and secured with set screws, which keeps mounting simple on commercial shafts. Send the full code by WhatsApp to confirm the exact variant.
- What information is needed to select a Y-bearing?
- Shaft diameter, housing type and operating conditions such as dust, moisture or washdowns. Those details define the series and the sealing. Without a code, a housing photo and the shaft measurement are enough for us to help.
- Is it possible to use a bearing from another brand instead?
- Often yes, as long as the bore, inner ring width, locking style and outer geometry correspond. Tolerances and sealing differ between manufacturers, so compare the data sheet before mounting. Ask us to review the equivalence.
