Dimensional Control
Precision Manufacturing & Dimensional Control
Manufactured using precision processing equipment to maintain consistent belt dimensions and tooth geometry.
±0.1 mmThickness tolerance
±0.2 mmWidth tolerance
Length deviation is controlled according to the applicable belt specification and manufacturing requirements. Confirm the required dimensions for each replacement or new application.
Tooth Profile Options
Timing Belt Tooth Profiles
The supplied profile reference includes traditional trapezoidal profiles and curvilinear / arc profiles. Profile selection should match the pulley and original belt specification.
Trapezoidal Timing Belts
T2.5, T5, T10 and T20 profiles are commonly used in traditional synchronous transmission systems.
Curvilinear / Arc Timing Belts
3M, 5M, 8M, 14M and 20M profiles use rounded tooth engagement and are widely used in modern industrial transmission systems.

Replacement Belt Identification
How to Identify Your Existing Timing Belt
A clear, repeatable check helps reduce uncertainty when the original model marking is missing.
Identify the Tooth Profile
Check whether the belt uses a trapezoidal or curvilinear / arc tooth profile.
Count the Teeth
Count the total number of teeth on the existing belt.
Measure the Pitch
Measure from the center of one tooth to the center of the next tooth.
Measure the Belt Length / Circumference
Measure the total belt circumference or confirm the pitch length from the marking.
Measure the Belt Width
Measure the belt width accurately using a caliper whenever possible.
If the original belt marking is still visible, send a clear photo of the printed model number.

FAQ
Questions Before Matching a Belt
Share the original belt information first whenever possible. It is the most direct basis for a replacement review.
Can timing belts be used with servo motors?
Yes. Timing belts are widely used in servo-driven automation systems because the toothed belt and pulley provide synchronized transmission without normal belt slip.
How do I identify my existing timing belt?
Check the printed model first. If the marking is unavailable, identify the tooth profile, pitch, tooth count, belt length and belt width.
What information is required for a quotation?
The belt model, pitch, number of teeth, width, quantity and application photos are recommended.
Can you supply non-standard belt widths?
Please send the required width and application details for evaluation.
Can you help identify a belt from photos?
Yes. Clear photos of the tooth profile, belt marking and overall belt can help with preliminary identification.
