3/4 Tapped Base Pillow Block Bearing SpinCo Iron Housing UCPA204-12

Description

Product Overview

The 3/4″ tapped base pillow block bearing from SpinCo is engineered for durability and ease of maintenance. Its cast iron housing offers exceptional rigidity, resisting deformation under heavy loads while providing a stable platform for the rotating shaft. The integrated grease zerk allows technicians to re‑lubricate the bearing without disassembly, extending service intervals and reducing downtime.

Designed with a wide inner ring, the bearing accommodates a 3/4″ shaft and features two set screws that lock the shaft firmly in place, preventing slippage during operation. The bolt hole spacing of 2 inches (50.8 mm) aligns with standard mounting patterns, enabling quick installation on a variety of machine frames and equipment bases.

Dimensions are carefully balanced for compactness and performance: overall length of 2.875 in (73.03 mm), shaft height of 1.31 in (33.3 mm), and overall height of 2.56 in (65.09 mm). The bolt size of 3/8″ ‑ 16 TPI with a 1/2″ depth ensures a secure connection to the mounting surface.

SpinCo’s commitment to quality is evident in the precision casting process, which eliminates porosity and ensures uniform material density throughout the housing. This results in a bearing that can withstand harsh industrial environments, including exposure to dust, moisture, and temperature fluctuations.

Interchangeability is a key advantage; the bearing matches part numbers from major manufacturers such as Peer (UCPAS204-12), AMI (UCTB204-12), Browning (VTBS-212), Dodge (TB‑SC‑012), and others, simplifying inventory management and replacement logistics for maintenance teams.

Usage

This pillow block bearing is ideally suited for power transmission applications across a wide range of industries, including manufacturing, material handling, and agricultural equipment. Its robust construction makes it a reliable choice for conveyor rollers, gear drives, and pump shafts where continuous operation and minimal vibration are critical.

In environments where regular maintenance is required, the grease zerk provides a convenient access point for adding lubricant without removing the bearing from its mount. This feature is especially valuable in hard‑to‑reach locations or in systems that operate continuously, such as assembly lines and processing plants.

Engineers often select this bearing for projects that demand precise alignment and repeatable performance. The tapped base design allows for fine‑tuning of shaft position, ensuring optimal load distribution and reducing wear on adjacent components.

Because the bearing conforms to standard bolt patterns, it can be retrofitted onto existing equipment with minimal modification. This flexibility helps extend the service life of older machinery while upgrading its performance to meet modern efficiency standards.

FAQ

What size shaft does this bearing accommodate?

The bearing is designed for a 3/4″ (19.05 mm) shaft diameter, providing a generous inner ring that accepts the shaft while allowing for precise positioning using the set screws.

How often should the bearing be lubricated?

Lubrication frequency depends on operating conditions, but for most industrial applications a monthly check is sufficient. The grease zerk allows you to add lubricant without removing the bearing, making routine maintenance quick and easy.

Can this bearing replace other manufacturers’ parts?

Yes. The bearing is interchangeable with several equivalent part numbers from Peer, AMI, Browning, Dodge, FAFNIR, IPTCI, Link Belt, NTN, and Sealmaster, allowing you to use it as a direct replacement in most existing installations.

Is the bearing suitable for high‑temperature environments?

The cast iron housing tolerates a wide temperature range, typically up to 200 °F (93 °C). For applications exceeding this range, consult our technical support for alternative material options.

What warranty does SpinCo provide?

SpinCo offers a one‑year limited warranty covering material defects and workmanship. Should any issue arise within the warranty period, contact our support team for a replacement or repair solution.
