Steel Deep Groove Ball Bearing 3.54in Bore 6.30in OD 1.18in Length

Overview

This steel deep groove ball bearing is engineered for high-speed industrial applications requiring reliable radial load support and precise rotational movement. Featuring a 3.54-inch bore diameter and a 6.30-inch outside diameter, the unit measures 1.18 inches in width to fit standard housing configurations found in heavy machinery. The C3 internal clearance specification is critical for operations involving elevated temperatures or high rotational speeds, as it accommodates thermal expansion of the rolling elements and minor shaft misalignment without compromising performance. Constructed from durable hardened steel, this component delivers extended service life and reduced maintenance intervals in demanding environments where structural integrity and consistent operation are paramount.

Key Features

C3 internal clearance designed for thermal expansion and high-speed operation Hardened steel construction ensures superior wear resistance and durability Optimized raceway geometry reduces friction and heat generation Precision-ground surfaces provide smooth rotation and minimal vibration Sealed design options available to protect against dust and moisture ingress Compatible with standard industrial shaft sizes measuring 3.54 inches

Specifications

Bore Diameter: 3.54 in Outside Diameter: 6.30 in Width: 1.18 in

Material

Hardened Steel Internal Clearance Class: C3 Load Type: Radial and moderate axial Pack Quantity: 1 unit

Applications

Electric motors and generators operating at high RPM Industrial pumps and compressors requiring continuous duty cycles Conveyor systems in manufacturing and logistics facilities Gearboxes and transmission units in heavy equipment Agricultural machinery exposed to variable load conditions HVAC blowers and fans needing reliable long-term performance Technical Notes The C3 clearance designation indicates an internal radial play greater than normal, which is essential for preventing preload issues caused by temperature differentials between the inner and outer rings. When installing this bearing, ensure the shaft tolerance matches the 3.54-inch bore specification to prevent slippage or excessive tightness. The hardened steel material provides a Rockwell hardness suitable for resisting deformation under significant radial loads. Regular lubrication schedules should be maintained according to the specific speed and load factors of the application to maximize the operational lifespan of the unit. This component serves as a direct replacement for standard metric series bearings converted to imperial measurements for use in North American industrial supply chains.
