TVN Series (200,300)

Mine Car & High-Temperature Plummer Blocks for Harsh Industrial Applications

JAYCO Engineering manufactures TVN Type Bearing Housings, specially designed for mine cars, rail-mounted equipment, mining conveyors, and high-temperature industrial applications. These rugged Plummer Block Housings are engineered to perform reliably under shock loads, dust, moisture, vibration, shaft misalignment, and extreme temperature conditions. Built for durability and low maintenance, JAYCO TVN housings provide long bearing life and dependable performance in the toughest operating environments.

Heavy-Duty Mine Car Bearing Housings

Designed for Mining, Rail & Rough Service Conditions

JAYCO TVN 200 and TVN 300 series housings are widely used as journal bearing units for mine cars and rail-mounted machinery, where alignment flexibility and robust construction are essential.

These housings are compatible with:

• Self-aligning ball bearings (1200 / 1300 series)
• Deep groove ball bearings (6200 / 6300 series)

The design ensures smooth operation even under continuous shock, vibration, and contaminated environments.

Available TVN Housing Designs

JAYCO supplies TVN housings in two standard configurations to suit different shaft arrangements.

Design A – Sealed End Cover

Ideal for shaft-end applications.

Design B – Open Cover

Designed for through-shaft applications where the shaft extends through the housing.

Benefits

• Suitable for continuous shaft assemblies
• Easy installation in conveyor and rail systems

Floating & Locating Bearing Arrangements

Both TVN housing designs are available as:

• Floating bearing units
• Locating bearing units

This allows flexibility in handling thermal expansion and shaft movement.
