Steel Deep Groove Ball Bearing 1.77in Bore 3.94in OD, Pkg Qty 2

Overview

This steel deep groove ball bearing is engineered to deliver exceptional performance in high-load industrial environments. Designed with precision-machined races and hardened steel construction, the unit ensures reliable rotational movement and precise shaft alignment under demanding conditions. The component features a 1.77-inch bore diameter and a 3.94-inch outside diameter, making it suitable for a wide range of heavy machinery and motor assemblies. With a compact width of 0.98 inches, this bearing fits seamlessly into space-constrained designs without compromising on load capacity or durability. Each package contains two units, providing a cost-effective solution for maintenance teams and original equipment manufacturers looking to minimize downtime and extend service intervals.

Key Features

Hardened steel construction provides superior resistance to wear and deformation Dual rubber seals effectively retain lubrication while excluding dust, moisture, and debris Precision-ground races ensure smooth rotation and reduced friction High radial load capacity supports heavy-duty mechanical applications Compact 0.98-inch width allows for installation in tight housing configurations Sold in pairs to facilitate simultaneous replacement and balanced performance

Material

Hardened Steel Seal Type: Dual Rubber (2RSR) Load Type: Radial and moderate Axial Package Quantity: 2 units

Applications

Electric motor end caps and rotor support systems Industrial gearboxes and transmission assemblies Agricultural machinery including harvesters and tractors Conveyor belt rollers and pulley systems Pump housings and fluid handling equipment HVAC blower wheels and fan shafts Automotive alternators and starter motors Textile manufacturing equipment and spinning frames This bearing series is specifically optimized for operations where continuous rotation and consistent load-bearing are critical. The dual-seal design significantly extends component life by preventing the ingress of abrasive particles that can cause premature failure. Whether used in new equipment manufacturing or as a direct replacement part during scheduled maintenance, this deep groove ball bearing offers the structural integrity required for rigorous industrial cycles. The standardized dimensions ensure compatibility with existing shafts and housings, simplifying the procurement process for facility managers and procurement specialists. By maintaining optimal lubrication levels internally, the unit reduces the need for frequent re-greasing, thereby lowering total cost of ownership over the lifespan of the machinery.
