Flexible plastic gear racks in 0.8 Mod (32DP) pitch. These racks can provide an easy to install rotational drive as high as approx 270 degrees for example on camera focus bands. They also offer an economical answer where a big gear is necessary or a longer stretch (up to 2 metres) of linear motion is preferred. These racks are compatible with our 0.8 Mod and 32 DP pitch Spur Gears.
EVER-POWER stock racks are made for high precision linear movement applications. You can expect a large selection of racks which range from module 0.5 to 10 and lengths from 100 to 2000 mm.
Hardened Surface Racks (MRGF – MRGFD) : Has the highest power and precision in the EVER-POWER standard rack series. Bolt holes could be remachined as carburizing is applied just within the tooth area. J Series products are also available.
Hardened Ground Racks (KRGF-H – KRGFD-H) : Temperature treated ground gears with high precision and power has excellent cost-overall performance ratio. J Series items are also available.
Hardened Racks (KRF-H/KRFD-H) : That is a solid rack manufactured from Chromoly steel, treated by carburizing. Has high-strength, high wear level of resistance, and allows downsizing of SR racks. J Series items are also available.
Hardened Racks (SRF-H/SRFD-H) : Stable Hardened racks with high strength, extended life span are affordable. J Series products are also available.
Thermal Refined Ground Racks (KRG – KRGF – KRGD) : High strength and abrasion-resistant for precision linear motion.
Metal Racks w/ Machined Ends (SRAF – SRAFD – SRAFK) : This gear rack gets the same tooth height and encounter width sizes, more compact and reasonably priced in comparison to SRF Racks
Steel Racks (SR) : Low cost, large selections of modules and quantity of teeth. J Series products are also available.
Steel Racks w/ Machined Ends (SRF) : Low priced, large selections of modules and number of tooth. J Series products are also available.
Racks with Bolt Holes (SRFD – SRFK) : Low cost, large selections of modules and amount of teeth. J Series items are also available.
STAINLESS Racks (SUR•SURF•SURFD) : Ideal for food machinery due to SUS304 materials\’s rust-resistant quality.
Plastic-type Racks (DRF/DRFD/DRFK) : Plastic racks with little dimensional change, absorb lower water than MC Nylon racks. J Series items are also available.
Plastic material Racks (PR•PRF) : Made form MC nylon, can be used without lubrication.
Brass Racks (BSR) : Small pitch racks manufactured from free-reducing brass, excellent workability and high rust resistance.
Steel Round Racks (SRO – SROS) : Convenient in applications where in fact the rack has the reciprocal movement. S Type is easy to install.
Stainless Steel Round Racks (SURO) : Same dimensions as SRO racks, except in stainless. Use where rust-resistance is required.
Ground Helical Racks (KRHG – KRHGF – KRHGFD) : Excellent items with high precision and power, and low noise and abrasion characteristics.
Metal Helical Racks (SRH – SRHF – SRHFD) : Effective in reducing noise and vibration because of larger contact ratio of helical gears.
Molded Versatile Racks (DR) : Used in applications because of its flexibility, where metallic racks do no possess this attribute. Pinions and components are also available.
Molded Flexible Rack Clamps (SRS) : Utilized to secure Molded Flexible Racks.
Molded Versatile Rack Pinions (SSDR) : Spur pinions used for molded versatile racks.
Flexible Rack Instruction Rails (ARL) : Guideline Rails for Molder Flexible Racks.
We offer as standard a wide selection of Racks in Metric and Imperial sizes. Spur Racks can be found in Steel (En8) or more to 2 metres long. STAINLESS and Delrin (Plastic-type) Racks are produced with Spur and Helical tooth forms, square and circular sections up to 400mm in length. Alternative materials can be found on request. Moulded Hostaform Racks can be found to offer a cost-effective alternative where much less torque is required.
Variable stiffness can enhance the capability of human-robot interacting. Predicated on the mechanism of a versatile rack and equipment, a rotational joint actuator called vsaFGR is proposed to modify the joint stiffness. The versatile gear rack could be regarded as a combination of a nonlinear elastic component and a linear adjusting system, providing benefits of compactness. The joint stiffness can be in the range of 217-3527 N.m/rad, and it is inversely proportional to the 4th-purchase of the gear displacement, and almost independent from the joint angular deflection, providing benefits of quick stiffness regulation in a brief displacement of 20 mm. The gear displacement with regards to the flexible equipment rack can be perpendicular to the joint loading drive, so the power necessary for stiffness regulating is as low as 14.4 W, providing advantages of energy saving. The high compactness, great stiffness range and low power cost of vsaFGR are proved by simulations and experiments.
Flexible plastic gear racks in 0.8 Mod (32DP) pitch. These racks can offer an easy to set up rotational drive as high as approx 270 degrees for example on camera focus rings. They also provide an economical option where a huge gear is required or a longer stretch (up to 2 metres) of linear movement is desired. These racks are appropriate for our 0.8 Mod and 32 DP pitch Spur Gears.

The gear displacement with regards to the flexible gear rack is definitely perpendicular to the joint loading pressure, so the power necessary for stiffness regulating is as low as 14.4 W, providing advantages of energy conservation.
