Steel Deep Groove Ball Bearing 1.57in Bore 3.15in OD 0.71in L, Pkg Qty 20

Overview

This industrial-grade deep groove ball bearing is engineered for high-speed rotational applications requiring precise radial load support and minimal friction. Constructed from hardened steel, the unit features a robust design capable of withstanding demanding mechanical environments found in heavy machinery and automated systems. The C3 internal clearance specification allows for optimal performance under elevated operating temperatures by accommodating thermal expansion without compromising rotational smoothness. Dual rubber seals are integrated on both sides to effectively retain lubrication within the raceway while excluding dust, moisture, and other particulate contaminants. This configuration ensures extended service life and reduced maintenance intervals for critical equipment.

Key Features

Hardened steel construction provides superior durability and wear resistance C3 internal clearance accommodates thermal expansion during high-temperature operation Dual rubber seals (2RS) prevent lubricant leakage and contaminant ingress Optimized for high-speed rotation with minimal friction and heat generation Consistent radial load capacity suitable for continuous duty cycles Sold in bulk packages of 20 units for efficient inventory management and large-scale installations

Material

Hardened Steel Seal Type: Double Rubber Seal (2RS) Internal Clearance: C3 Load Type: Radial Package Quantity: 20 units

Applications

Electric motor shafts and spindle assemblies Industrial gearbox and transmission systems Conveyor belt rollers and pulley mechanisms Agricultural machinery drive trains HVAC fan motors and blower wheels Pump housings and fluid handling equipment Textile manufacturing machinery Packaging and sorting automation lines This component serves as a critical replacement or original equipment part for facilities requiring reliable motion control. The precise dimensions ensure a direct fit for standard 1.57-inch shafts, while the 3.15-inch outer diameter aligns with common housing bores. The 0.71-inch width offers a compact profile that fits within tight mechanical envelopes without sacrificing load-bearing capability. By utilizing a C3 clearance grade, these bearings are particularly well-suited for applications where operating temperatures frequently exceed standard ambient conditions, such as near furnaces, in high-friction gear sets, or in environments with significant heat soak from adjacent components. The sealed design eliminates the need for frequent re-lubrication, making them ideal for hard-to-reach locations or systems designed for long-term unattended operation. Bulk packaging supports procurement strategies for maintenance teams managing large fleets of machinery, ensuring parts availability for scheduled overhauls or emergency repairs.
