FAQ

A: If the item is in stock, it's usually 5-10 days. If the item is not in stock, it's 15-20 days, depending on the quantity.

A: Yes, we can provide free samples, but we don't cover the shipping costs.

A: Gear racks are linear motion components used in various industrial applications. They provide a straight, toothed track for gears or pinions to engage with, converting rotary motion into linear motion.

A: Clamp the gear rack to the machine bed in the area of the fixing holes. Insert the first fixing screw in the direction of installation. Tighten the fixing screw with an appropriate torque in the direction of installation. Repeat the previous steps for the remaining fixing screws.

A: High pitch error: Gear racks with hardened teeth, due to the tooth deformation that occurs during the hardening process. Typical error of 0.20 mm per meter. - Medium pitch error: Gear racks with milled teeth. Typical error of 0.10 to 0.15 mm per meter.

A: A steering rack is a key component in your vehicle's steering system, translating the rotational movement of your steering wheel into linear movement, which directs your car's wheels. It consists of a metal rod with gear teeth and is usually paired with a power steering system to make steering easier.

A: When selecting a rack and pinion drive for an application, it is important to consider all of the applications parameters to determine the forces, speeds and accuracy required. Once these are defined, it is possible to select the best rack and pinion drive solution to meet the application requirements.

A: Carbon steel is an ideal choice because it provides excellent strength relative to the rack tooth and the pinion itself. High-quality rack and pinion gears are often subject to heat treatment before use.

A: A gear rack is a cylindrical gear with the radius of the pitch cylinder being infinite. By meshing with a cylindrical gear pinion, it converts rotational motion into linear motion. Gear racks can be broadly divided into straight tooth racks and helical tooth racks, but both have straight tooth lines.

A: One approach is to switch to oil-spray lubrication, though this can become messy. Instead, it's recommended that rack-and-pinion sets be grease lubricated and then protected with bellows or way covers, or installed in an inverted position so that debris falls off the working gear surfaces.
