Product Description

Deep Groove Ball Bearing 62306-2RSR Sealed 30x72x27mm for Electric Motors and Industrial Pumps

Product Overview

The 62306-2RSR Deep Groove Ball Bearing is a wide-series single-row ball bearing equipped with dual contact lip seals for superior protection against dust, dirt, and moisture. Engineered to support heavy radial loads and moderate axial loads in both directions, it is widely used in industrial electric motors, centrifugal pumps, and agricultural gearboxes where extended grease life and reliable sealing are strictly required.

Key Advantages

Wide inner and outer ring design provides an enlarged grease reservoir for longer maintenance-free service life.
Dual rubber lip seals (2RSR) prevent dust, water, and contaminants from entering while retaining factory-filled lubricant.
High load-carrying capacity supports heavy radial forces and bi-directional axial loads during continuous operation.
Low friction and smooth running achieved through precision-ground raceways and high-grade chrome steel balls.
Custom clearance and grease options available (such as C3 radial clearance or high-temperature synthetic grease).

FAQ

Q1: Can you provide custom bearings or special grease fills?
Yes, we support OEM and custom production based on drawings, including C3 radial internal clearance, high-temperature Viton seals, and specialty synthetic greases.

Q2: What is the difference between the 62306-2RSR and the standard 6306-2RSR?
Both share the same 30 mm bore and 72 mm outer diameter, but the 62306-2RSR features a wider 27 mm width (compared to 19 mm on the 6306-2RSR), providing a larger grease chamber for extended maintenance-free operation.

Q3: Is the 62306-2RSR interchangeable with 62306-2RS1 or 62306 DDU?
Yes, "2RSR" (INA/FAG suffix) indicates dual contact NBR rubber seals on both sides, making it fully interchangeable with SKF's 62306-2RS1 and NSK's 62306 DDU.

Q4: What quality certifications do your bearings hold?
Our manufacturing facilities operate strictly under ISO 9001 and IATF 16949 quality management standards to ensure full traceability and consistent industrial quality.

Q5: What are your shipping terms and delivery times?
We support EXW, FOB, CIF, and DDP terms via sea, air freight, or international express. Standard models ship within 7–15 days, while custom batches take 25–45 days.
