FAQs: Pulleys for Automation Applications

We provide comprehensive finishing solutions tailored to the needs of each precision bearing component. These include precision cylindrical grinding to attain surface finishes below 4 Ra microinches on raceways with stock removal for dimensional accuracy control, superfinishing with abrasive stones to below 2 Ra microinches to create ultra-smooth surfaces for lower friction and extended life, lapping for bearing faces to attain mirror finishes and flatness within 0.0001 inches, through-hardening heat treatment to attain 58 to 63 HRC hardness on 52100 steel with tempering for toughness, case hardening for selective hardening of raceway surfaces while leaving ductile cores, black oxide coating for light corrosion protection and break-in lubrication retention, phosphate coating for temporary corrosion protection during storage and shipping, passivation on stainless steel to remove free iron and to enhance corrosion resistance, and specialized coatings like titanium nitride (TiN) and diamond-like carbon (DLC) for extreme wear applications or dry running conditions where conventional lubrication is used.

All components under ISO 9001 quality management systems manufacturing with traceable complete materials, measurement of dimensional design specification verification, tooth profile symmetric timing belt pulleys ISO 5294 compliance, dynamic balance testing, and power 1 to 500 Newton-meters position synchronous torque controlled belt drive with 5000 hours belt life.

Yes. We offer flexible manufacturing capabilities including:

There is ±0.001 inches of tolerance to accommodate the pitch of the teeth for synchronous motion and engagement of the belt, ±0.0005 inches for the bore diameters to ensure proper shaft fit, and for runout control, pitch circle bore and pitch circle concentricity is within 0.001 inches. TIR is also 0.002 inches, outside diameter is ±0.005 inches, and the balance is also to grade G6.3.

Automation pulleys are parts in a power transmission system that moves belts in robotic drives, linear actuators, and conveyor systems. Automation pulleys can be timing belt pulleys where trapezoidal teeth cut for HTD, GT2, and AT profile belts for positive engagement, synchronous belt pulleys to prevent slippage in positioning applications, V-belt sheaves that grip the belt for industrial drives, flat belt pulleys for low speed applications, grooved pulleys for X-Y positioning with a round belt, step pulleys to change speed with multiple diameters, idler pulleys to tension and direct a belt, and custom pulleys that can be multi-groove, have integrated flanges to keep a belt on track, and have pulleys with keyways, set screws, or clamping hubs to belts.

The main advantages of Aluminum 6061-T6 and 7075-T6 are a 65% reduction in weight making quicker rotational speed changes possible and quicker acceleration and deceleration, very good machinability for making accurate tooth profiles, torque resistance up to 50 Newton-meters making them strong enough, and having natural corrosion resistance. The strength alternatives for pulleys are steels 1045 and 4140, which also increase maximum torque capacity to over 500 Newton-meters, are very wear-resistant on tooth flank, and are cost-effective for industrial through-hardening and wear-out applications. The 303 grade of stainless steel provides strength and non-coring corrosion resistance for food processing, cleanroom, and grade 5 stainless for strength to non-magnetic food processing, making it a cleanroom and food processing environment, adding to versatility. In engineering plastics cost-effective with low-torque precision applications, Delrin and nylon are quiet (5 to 10 dB) and wear-friendly (minimizing surface wear) and provide belt-friendly surfaces, lowering overall wear, quiet operation, and also lightweight construction.
