Industrial spur gear and pinion for chain drive systems. This listing is for 1 piece of a 04C chain gear with a 30 tooth count, designed for motor chain drive sprockets. It features a 6.35 mm tooth pitch, a 10 mm bore, and is made from 45# steel for strength and durability in industrial applications. The gear is suitable for use with a range of teeth from 20T to 30T, with 30T as the current size. Key benefits Robust construction: 45# steel provides reliable strength for demanding industrial use and long service life. Precise engagement: the spur pinion design promotes accurate tooth contact with minimal backlash, helping reduce wear on the chain. Standardized fit: 6.35 mm (1/4 inch) tooth pitch and 10 mm bore enable straightforward compatibility and mounting in compatible drive systems. Compact, singlepiece design: simple installation with fewer parts and reduced risk of misalignment. Key attributes Gear type: Pinion spur gear Chain compatibility: 04C chain gear Teeth: 30 teeth (range 20T30T available) Tooth pitch: 6.35 mm Bore: 10 mm Material: 45# steel Piece count: 1 piece Application: Industrial sprocket wheel for motor chain drive Applications and use cases Conveyor or material handling drives in manufacturing lines that use 04C chain and require a 30tooth spur gear with a 10 mm shaft bore. Robotic or CNC machinery where reliable chain drive performance is needed and space is limited, using a 6.35 mm pitch chain. Small to mid sized industrial equipment, such as packaging machines or agricultural equipment, that rely on a durable spur gear to transfer motor torque through a chain drive. Notes This listing specifies 1 piece with 30 teeth, and notes that the series supports a 20T30T range. Ensure compatibility with your existing chain, shaft bore, and mounting configuration before ordering.
