The RBC 7612 DLG is a high-precision single row Angular Contact Ball Bearing engineered for demanding industrial applications requiring exceptional rigidity and precise shaft guidance. Featuring a 60mm bore, 110mm outer diameter, and a standard width of 22mm, this bearing utilizes a 40° contact angle (D) optimized for superior axial load capacity in one direction, combined with robust radial load support. The DLG suffix denotes a design optimized for high-speed operation and reduced friction, typically utilizing a universally matchable (G) design allowing for flexible arrangement into duplex pairs (back-to-back, face-to-face, or tandem) with standardized light (L) internal preload.
Designed primarily for mission-critical machinery in MRO and OEM environments, the 7612 DLG ensures maximum operational uptime in applications such as industrial pumps, high-speed gearboxes, woodworking spindles, and machine tool feed screws. Manufactured using high-grade, stabilized bearing steel and often equipped with a robust polyimide or machined brass cage for superior thermal stability and lubricant retention, this bearing minimizes vibrational impact and heat generation. Choosing the RBC 7612 DLG guarantees predictable performance, extended service life, and lower total cost of ownership (TCO) compared to standard commercial series bearings.
Key Features
Universal Match Geometry (G): Allows for flexible installation in tandem, face-to-face (O), or back-to-back (X) arrangements.
40° Contact Angle (D): Optimized for high thrust loads and superior axial rigidity, ideal for cantilevered shafts.
Light Preload (L): Reduces rolling friction and heat generation, increasing limiting speeds for continuous operation.
High Precision Tolerance (P5/ABEC 5 Equivalent): Ensures minimal runout and vibration, critical for machine tool accuracy.
Superior Load Ratings: High dynamic and static capacity relative to standard deep groove ball bearings of comparable size.
High-Grade Material: Manufactured from case-hardened or through-hardened steel for extended fatigue life.
