Thomson Industries Inc.

Thomson Industries Inc. A162536 Linear Ball Bearing 1 in 350 lbf

SKU CH-W0B3-F6XE4

Precision steel linear ball bearing with 1-inch bore, 350 lbf dynamic load capacity and 10 fps steady-state speed for inch-series motion systems

  • Precision 1 in linear motion with ±0.0005 in tolerance
  • 350 lbf dynamic and static load capacity for heavy radial forces
  • Closed steel bearing resists contamination in harsh environments
  • Operates from 0 to 500 °F across extreme temperature ranges
  • Steady 10 fps and accelerated 450 fps speeds for versatile applications

Precision linear bearing for inch systems

The Thomson A162536 is a closed-type linear ball bearing built to inch dimensions with a 1 in inside diameter and 1 9/16 in outside diameter. It suits precision motion assemblies that require a 2 1/4 in overall length and a -0.0005 in inside diameter tolerance. Engineers specifying steel bearings for linear guides will find the 350 lbf dynamic and static load ratings match moderate-duty requirements. Buyers needing self-aligning capability or a different bore size should select another series.

Thermal range and speed limits

The bearing operates continuously between 0 Degrees F and 500 Degrees F, covering typical industrial environments without special cooling. Steady-state linear speed is rated at 10 fps, while brief accelerated moves up to 450 fps are permissible. Dynamic and static load capacities are both 350 lbf, so the same figure governs sizing whether the axis is moving or holding position. Applications exceeding these temperatures or speeds require a different bearing class.

Closed design simplifies sealing

The closed ball-bearing construction keeps lubricant in and contaminants out without external seals, reducing assembly parts. No self-alignment feature is present, so shaft straightness and housing bore alignment must be controlled by the machine design. The precision series designation and tight ID tolerance support repeatable positioning in automated equipment. Users who need integral wipers or adjustable clearance must choose an alternative configuration.

Questions about this item

How do I press the 1 in linear ball bearing into its housing without damaging the .0005 in tolerance?

Freeze the bearing and warm the housing for a light shrink fit. Press only on the outer race with a sleeve that matches the 1 9/16 in OD. Never strike the balls or seals.

When should I plan to re-lubricate or replace the closed precision bearing?

The closed design holds factory grease for the life of the bearing under normal loads. Inspect seals at each scheduled shutdown; replace the unit if seal damage or noise appears.

What is the first limit I will hit if I run the bearing continuously at high speed?

The 500 °F maximum operating temperature is reached before the 450 fps accelerated speed rating. Monitor housing temperature; add cooling or reduce duty cycle if it approaches that limit.
