Rubber Timing Belts
Synchronous rubber belts for compact power transmission, positioning, and matched pulley systems.

Engineering review
SINOF reviews belt profile, width, effective length, operating environment, load, speed, and pulley data before confirming a belt proposal.
- MXL, XL, L, H, and XH trapezoidal profiles
- HTD 3M, 5M, 8M, 14M, and 20M profiles
- S2M, S3M, S5M, S8M, and S14M profiles
- T2.5, T5, and T10 profiles, plus double-sided and open-ended forms
Materials and precision
Profile, pitch, width, effective length, and matched-pulley requirements are confirmed for each inquiry.
- Rubber belt body with tensile-member construction
- Tooth-facing fabric and cord options reviewed for the application
Customization inputs
- Profile, belt width, and effective length
- Endless, double-sided, or open-ended form
- Surface and tooth-facing requirements
- Matched timing-pulley review
Inspection
- Profile, width, length, and visible-condition checks against the agreed specification
- Fit review with supplied or specified pulley data when included in the project
- Batch documentation defined during quotation
Frequently asked questions
Which information is needed for a rubber timing belt inquiry?
Please provide the profile, width, effective length or tooth count, quantity, operating conditions, and available pulley data.
Are double-sided and open-ended belts available for review?
Yes. Double-sided and open-ended forms can be reviewed against the requested profile, length, and application.
