The SKF Y-bearing XGG KTTB series is a sealed insert with a spherical outer ring and set screw locking, made to fit into split plummer block or flanged housings. It suits shafts turning at moderate speeds where a self-aligning unit that mounts easily and comes apart quickly is required. The seal keeps out dust and moisture, so it holds up in tough industrial settings. MR Industrial Accessories supplies this line.

The series code uses letters and numbers to show the insert type and its options. Take XGG1014KTTB, XGG1100KTTB, and XGG1108KTTB: the XGG prefix marks Y-bearings with a spherical outer ring. The middle digits give the bore size and bore style. The KTTB suffix covers sealing and locking: K for a tapered or cylindrical bore depending on the case, TT for a double-lip seal, and B for set screws on the inner ring. Reading these codes lets you order the exact replacement.

These bearings appear in belt conveyors, bucket elevators, mixers, mills, conveyor belts, and agricultural machinery. In food plants, cement plants, quarries, and poultry facilities, dust and moisture call for sealed units. You also find them in pumping equipment, fans, and low-power transmission systems. Self-alignment plus set screw locking makes mounting on commercial shafts straightforward and cuts downtime during corrective maintenance.

To pick the right Y-bearing, check the shaft diameter and the housing where it will sit. The KTTB seal guards against contaminants, but in very wet or gritty conditions, consider extra seals. When mounting, clean the shaft and apply a thin film of lubricant before inserting the bearing. Tighten the set screws evenly to the recommended torque to prevent distortion. Verify housing alignment and leave axial clearance for thermal expansion. Regular greasing with quality grease helps service life.

Y-bearings follow international standards, so units from different brands can often be swapped if the main dimensions match: bore, outer diameter, width, and locking type. Sealing suffixes and tolerances may differ between makers, so compare specifications before replacing. For SKF, the XGG KTTB series keeps its naming, but other brands may use different codes for the same setup. Ask us if interchangeability is unclear.
