The SINOCONVE AT20 Rubber Timing Belt uses a T-Type tooth profile for positive engagement with a matching timing pulley. Its confirmed pitch is 20 mm, tooth height is 5.00 mm, and belt thickness is 8.00 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.
AT20 is a T-Type rubber timing belt with a confirmed pitch of 20 mm, tooth height of 5.00 mm, and belt thickness of 8.00 mm. It is designed for reinforced trapezoidal tooth loading and dynamic positioning in high-dynamic automation, industrial indexing, packaging machinery, positioning equipment, and reinforced trapezoidal drives. 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.
