About the 6311 deep groove ball bearing
The 6311 is a deep groove ball bearing with a 55 mm bore, 120 mm outside diameter and 29 mm width. It is made at our plant near Rajkot, Gujarat, from forged steel rings through heat treatment, grinding, assembly and final inspection, to P0 (normal) or P6 precision under ISO 9001:2015.
The designation 6311 follows standard ISO boundary dimensions, so a GBI 6311 fits the same housing and shaft as a 6311 from SKF, FAG, NSK, NTN, Timken or any other brand. Check seal, cage and clearance requirements with our team before replacing a branded part.
We supply the 6311 to OEMs, distributors and maintenance buyers across India, with delivery to every state, and export it worldwide. See export terms or ask for a bulk quote.
