SINOCONVE S2M STPD/STS-Type Arc Tooth Rubber Timing Belt for Precision Electronics Equipment with Smooth Low-Noise Engagement
S2M STS-Type Rubber Timing Belt for Synchronous Transmission
The SINOCONVE S2M Rubber Timing Belt uses a STS-Type tooth profile for positive engagement with a matching timing pulley. Its confirmed pitch is 2 mm, tooth height is 0.76 mm, and belt thickness is 1.36 mm.
The belt body is made from high-quality synthetic CR rubber. Fiberglass cord controls belt elongation, and a highly wear-resistant nylon elastic fabric protects the tooth contact surface. This construction is intended for synchronized motion, fixed speed ratio, repeatable positioning, and slip-free power transmission when the tooth profile, pulley, tension, and operating load are correctly matched.

S2M STS-Type Tooth Rubber Timing Belt
S2M is a STS-Type rubber timing belt with a confirmed pitch of 2 mm, tooth height of 0.76 mm, and belt thickness of 1.36 mm. It is designed for smooth curvilinear engagement and precision motion control in automation, robotics, precision positioning, packaging lines, assembly equipment, and smooth-motion synchronous systems. The belt body uses high-quality synthetic CR rubber, reinforced with fiberglass cord, while the teeth are protected by highly wear-resistant nylon elastic fabric. This construction supports accurate synchronous transmission without normal operating slip, together with resistance to cracking, ozone, aging, heat, wear, and repeated dynamic bending. The tooth profile, pitch, belt width, teeth number, pulley geometry, speed, torque, and installation tension must be confirmed before production.
