Caster Installation Height and Installation Guidelines
Time：Nov 03,2025
Selecting the right caster specifications is just the first step—proper installation is the key to ensuring smooth, effortless movement of your cart (or equipment) and extending the lifespan of the casters. Below, we’ll clearly explain, in one go, how to measure "installation height," along with 5 often-overlooked installation details. Follow these guidelines carefully, and you’ll significantly reduce future repair and replacement costs.
I. What is "Installation Height"?
1. Plate-type (Omni-directional/Orientable) Casters
Installation height refers to the vertical distance from the bottom surface of the mounting plate to the lowest point of the wheel—essentially, the amount by which the equipment is lifted after the casters are installed.
2. Screw-type casters (including screw-brake wheels)
There are two sizes to keep straight:
A. Total height—from the top of the lead screw to the lowest point of the wheel
B. Installation Height – Distance from the equipment base to the lowest point of the wheels
The thickness of the equipment's bottom surface varies, which affects the B-value. Be sure to calculate this in advance to avoid height mismatches after installation.
II. 5 Core Installation Precautions
1. Stay level
The entire machine must be placed horizontally before locking the casters, to prevent uneven stress that could cause the frame to deform.
2. The swivel wheel's rotating axis is perpendicular to the ground.
Misaligned installation increases rotational resistance, causes "drift," and accelerates bearing wear.
3. Ensure the fastener "fits snugly" before tightening further
- Select and install bolts, washers, and spring washers that match the hole diameter.
- Tighten using a torque wrench according to the manufacturer's recommended torque; overtightening may crack the spindle, while insufficient tightening could cause it to wobble.
4. First "release the brake," then install the brake wheel.
If you tighten the screws while the brakes are locked, the brake pads will be compressed and deformed, leading to issues like ineffective braking or unusual noises later on.
5. Matching in the same specification
When possible, select universal and directional wheels of the same brand, material, and diameter for a single vehicle, ensuring even load distribution and smooth maneuverability.
III. 2 Essential Actions to Perform After Assembly
1. Empty-load operation: Check whether steering is smooth and free of any sticking or jamming.
2. Full-load testing: Observe whether any shaking, unusual noises, or brake failures occur
Confirm everything is normal before starting formal operations—this will effectively prevent rework later on. Wishing you a smooth installation and long-lasting durability for the casters!
