1-1/16″ Four Bolt Flange Bearing by SpinCo – Grease Zerk, Heavy Duty

Description

Product Overview

The 1-1/16″ four bolt flange bearing from SpinCo is engineered for demanding industrial environments where reliability, durability, and ease of maintenance are paramount. Constructed from high‑grade cast iron, the housing offers exceptional rigidity and resistance to wear, while the integrated grease zerk provides a convenient point for re‑lubrication without disassembly. The bearing’s wide inner ring accommodates a 1-1/16″ bore, and two precision‑machined set screws secure the bearing to the shaft, ensuring consistent alignment and load distribution. Dimensions are carefully balanced: a bolt‑hole‑to‑bolt‑hole span of 3.267 in. (83 mm), overall length of 4.252 in. (108 mm), and a thickness of 1.582 in. (40.2 mm) deliver a compact yet robust solution for a variety of power transmission applications. Designed to meet the rigorous standards of the industrial sector, this flange bearing is a versatile component for machinery ranging from conveyors and gearboxes to pumps and mixers.

Usage

SpinCo’s four bolt flange bearing excels in settings where continuous operation and high torque transmission are required. It is ideally suited for heavy‑duty equipment such as industrial conveyors, motor‑driven gearboxes, and high‑speed pumps that demand precise shaft alignment and minimal downtime. The bearing’s robust cast‑iron housing tolerates temperature fluctuations and abrasive environments, making it a reliable choice for factories, processing plants, and outdoor installations exposed to dust, moisture, or chemical exposure. Maintenance crews benefit from the grease zerk, which allows quick replenishment of lubrication, extending service intervals and reducing the risk of unexpected failures. Whether retrofitting existing machinery or integrating into new designs, the bearing’s standardized dimensions and bolt pattern simplify installation and ensure compatibility with a wide range of shaft sizes and mounting configurations.

FAQ

What size shaft can this bearing accommodate?

The bearing is designed for a 1‑1/16″ (approximately 27 mm) bore, making it compatible with shafts of that exact diameter. The wide inner ring provides additional clearance for minor variations, ensuring a snug fit when secured with the set screws.

How often should the bearing be lubricated?

Lubrication frequency depends on operating conditions such as load, speed, and environment. For typical industrial applications, re‑lubricating every 6‑12 months using the built‑in grease zerk is recommended. In harsher conditions, more frequent maintenance may be necessary.

Can this bearing be used in high‑temperature environments?

Yes, the cast‑iron housing and high‑temperature‑rated grease compatible with the zerk can operate safely up to approximately 200 °F (93 °C). For temperatures exceeding this range, consult SpinCo for a bearing variant with specialized materials.

Is the bearing compatible with existing mounting brackets?

The bearing’s bolt‑hole‑to‑bolt‑hole dimension of 3.267 in. (83 mm) aligns with standard flange mounting brackets used in most industrial machinery. Verify the bracket’s bolt pattern before installation to ensure a proper fit.

What warranty does SpinCo provide?

SpinCo offers a limited one‑year warranty covering manufacturing defects and material failures under normal operating conditions. This warranty reflects our confidence in the product’s quality and provides customers with added assurance.
