Choosing The Proper Caster or Wheel

How To Specify Casters For Direct Replacement

When existing casters of acceptable performance are in use, furnish a part number. Our Expert Customer Service Department can recommend an accurate, direct replacement.

Note: Send us a sample for free no obligation identification. Sample returned freight prepaid same day if necessary.

How To Specify Casters For New Applications

1. How much load capacity is required?

Divide the load capacity needed by the number of casters being used to get the capacity per caster.

Example:

1,000 lbs. total load ÷ 4 casters used = 250 lbs. per caster.

Will the load be subject to shock or impact, or will the application involve towing?

2. What diameter and tread width is required?

The best and easiest way to improve rollability is to choose the largest diameter wheel that is practical for the application.

3. Type of mounting required?

A. If plate mount, what is the top plate and bolt hole pattern?

If the casters are being welded, the above dimensions are not critical.

B. If stem mount, type of stem (i.e. threaded, grip ring, (expandable).

1. Outside dimension of tubing?

2. Inside dimension of tubing?

3. Gauge or thickness of tubing?

4. Actual stem dimensions?

Note: See page 130 for tubing and pipe sizes, wire gauge chart, and decimal cross references.

4. Is the overall height critical?

Refer to page 7.

5. What is the operating environment?

See Wheel Material Selection Guide and Wheel Characteristics Selection Guide on pages 10, 11&12.

Some applications may require special wheel materials, bearing types or swivel and rigid horn types (i.e. temperature extremes, moisture, caustic chemicals, variance in floor condition).

Divide the load capacity needed by the number of wheels being used to get the capacity per wheel.

Example:

1,000 lbs total load ÷ 2 wheels used = 500 lbs. per wheel.

2. What diameter and tread width is required?

3. What hub length is required and is it offset or symmetrical?

4. What is the bore size?

5. What type of bearing is required?

6. What is the operating environment?

See Wheel Selection Guide on page 10.

7. Do you need component parts to mount wheel?

See Component Parts on pages 101 to 103.
