Industrial Flanged Ball Bearings Supplier

Flanged ball bearings are a type of single-row rolling bearing that include a flange (rim-like extension) on the outer ring. This flange is an integrated lip or collar on one side of the bearing’s outer circumference. The primary purpose of the flange is to facilitate locating the bearing in a housing and to secure it axially without needing additional components. In other words, a flanged ball bearing can be inserted into a simple straight bore (through-hole) and the flange will seat against the housing face, eliminating the need for a step/shoulder in the housing or separate retaining rings

Flanged ball bearings should not be confused with flanged bearing units (which are bearings already mounted in a flanged housing ready for bolting). Instead, flanged ball bearings are standalone bearings that simply have a modified outer ring. They are widely used in industrial and mechanical applications where ease of assembly and precise positioning are important

Apart from the flange, these bearings are constructed similarly to standard ball bearings. Their part numbers reflect this with a prefix or suffix like "F" or "MF" (for miniature metric types). Similar to standard ball bearings, these products can be offered in open, shielded, or sealed configurations for lubrication retention and contaminant protection. Letters like Z or ZZ indicate metal shields on one or both sides of the bearing, while RS/2RS (or RZ/2RZ) indicate rubber seals (contact or low-contact) on one or both sides
