Precision gears and gear racks

A gear is a toothed component that transmits rotary motion and force between shafts, while a gear rack is a straight toothed bar that converts rotary motion into linear movement when it meshes with a matching gear.

BEGE supplies spur gears, bevel gears, and gear racks built for precise transmission from rotary motion to either linear or right-angle motion. These components form the mechanical link inside a drive system that determines speed, direction, and positioning accuracy. When gears and gear racks are not accurately matched, a drive system loses precision and wears out components faster than intended.

A spur gear has straight teeth cut parallel to the shaft axis and transmits motion between two parallel shafts, which is why BEGE’s TW series meshes gears directly for a solid, low-maintenance rotary transmission. A bevel gear, also known as a conical gear, has teeth cut into a cone shape so it can transfer power between two shafts set at an angle to each other.

BEGE’s CTW bevel gear series covers gear ratios up to 5:1 for this kind of right-angle transmission. Choose a spur gear for straight-line rotary drives and a bevel gear whenever the drive direction needs to change angle.

BEGE offers six series across steel, stainless steel and plastic construction, covering rotary, right-angle, and linear motion needs within one supplier. The table below lists module range, tooth or pitch specification, size range, and material for each series, making it easier to shortlist a series before requesting a quote.

Plastic gears such as BEGE’s TWK, CTWK, and THK series run lighter and quieter than their steel equivalents, which matters in applications where noise reduction or reduced inertia is a priority. Self-lubricating properties in the plastic gear rack series lower maintenance requirements, since the components need less external lubrication to keep running smoothly.

Steel and stainless steel gears, by contrast, generally handle higher loads and offer greater rigidity, which suits heavy-duty drive systems better than plastic. The right material choice depends on load, speed, hygiene requirements, and how much noise the application can tolerate.

Yes. BEGE supplies FDA-certified plastic gears specifically for food-processing machinery, where direct contact between the gear and the food product is unavoidable. These food-safe gears are used in bakery production, dairy processing, and meat processing lines, sectors where hygiene standards rule out standard uncoated steel components. Because the plastic series also runs quieter and requires less lubrication, it fits the sanitation routines common in food plants better than a metal alternative would.

BEGE’s gears and gear racks serve mechanical engineering, industrial automation, robotics, food processing, and medical equipment manufacturing.

In mechanical engineering, they support packaging machinery and control motion in lifting systems and factory conveyors. In automation and robotics, gears control speed and direction in conveyor belts and robotic arms, including the joints and drive systems that determine a robot’s movement precision. In medical equipment, gears deliver the precision and reliability required in surgical robots, diagnostic machines, and laboratory or implant manufacturing equipment.

Start with the type of motion conversion needed: a spur gear for parallel-shaft rotary transmission, a bevel gear for right-angle transmission, or a gear rack when rotary motion needs to become linear displacement.

Next, match the module and tooth count to the required torque and positioning accuracy, since BEGE’s spur gears range from module 1 to 5 with 12 to 127 teeth depending on the series. Material choice follows from the operating environment: steel or stainless steel for heavy loads, and FDA-certified plastic for food contact or noise-sensitive settings. Bore size and gear rack length also need to match the existing shaft and travel distance before ordering.

Yes. BEGE produces customer-specific gear racks, spur gears, and bevel gears in steel, stainless steel, or plastic, built to specific dimensions and designs beyond the standard catalogue range. Custom options include a deviating bore, a keyway, a tapped hole, non-standard tooth counts, and specific surface finishes. This customer-focused approach is built for complex drive technology projects where a standard module or bore size does not fit the machine design. An extensive inventory and rapid delivery back up both the standard and custom ranges, keeping production continuity intact.

BEGE’s CTW bevel gear series covers gear ratios from 1:1 up to 5:1 for steel right-angle transmissions, with module sizes from 1 to 5 and tooth counts from 16 to 64. The plastic CTWK bevel gear series covers a narrower ratio range of 1:1 to 1:4, with tooth counts from 15 to 64, suited to lighter-duty right-angle applications.

Selecting the correct ratio determines how much the output speed and torque change relative to the input shaft, which needs to match the target machine’s design specification. For ratios or bore sizes outside these standard ranges, BEGE’s custom gear program can produce a matching bevel gear.

BEGE maintains an extensive, stable inventory of spur gears, bevel gears, and gear racks, which supports rapid delivery of the correct version straight from stock. The range spans steel, stainless steel, and FDA-certified plastic across six product series, giving machine builders one supplier for rotary, right-angle, and linear motion components instead of sourcing each type separately.

Custom-made gears are available on top of the standard range for projects with non-standard dimensions or requirements. Start with the product overview for spur gears, bevel gears, or gear racks to compare specifications before requesting a quote.
