• Hardened pinions paired with ISO 10 hardened racks provide long service life and consistent accuracy
• Pinions can be directly mounted to SureGear® gearboxes, simplifying system design and alignment
• 1‑meter rack sections support modular installation and easy system expansion
• Rack installation gauges available to ensure proper alignment when installing multiple rack sections
• One of the most cost‑effective linear motion solutions for travel lengths greater than 2 meters

Stainless steel worm gearboxes (speed reducers) drive a load at a reduced ratio of motor speed, with housings suitable for food and beverage applications. Output torque is increased by that same ratio; horsepower is unchanged (less efficiency losses).

Cast iron worm gearboxes (speed reducers) drive a load at a reduced ratio of the motor speed, with rugged housings to withstand industrial environments. Output torque is increased by that same ratio, while horsepower is unchanged (less efficiency losses).

Aluminum worm gearboxes with NEMA input faces are lower-cost, medium-duty worm gearbox alternatives that feature a lightweight construction, and hollow-shaft outputs. These gearboxes mate directly to NEMA C-face and TC-face motors.

• 30mm to 75mm center distances (frame sizes)
• 10:1 to 100:1 ratios (in most sizes)
• 56C, 145TC, and 182/4TC input faces
• Hollow shaft output with single or double output shafts optional

Aluminum worm gearboxes with IEC input faces are lower-cost, medium-duty worm gearbox alternatives that feature a lightweight construction, and hollow-shaft outputs. These gearboxes mate directly to IEC B5 and B14 faced motors.

• 30mm to 75mm center distances (frame sizes)
• 10:1 to 100:1 ratios (in most sizes)
• IEC input face types: B5 & B14
  (to fit IEC motor frame sizes: 63, 71, 80, and 90)
• Hollow shaft output with single or double output shafts optional

Cast iron helical gearboxes deliver smooth, efficient power transmission with high load capacity and flexible mounting for demanding industrial applications.

• Double‑lipped oil seals help prevent leakage
• Mountable in multiple orientations for installation flexibility

Compact inline strain wave gearboxes deliver extremely high reduction ratios with zero backlash and long service life in space‑constrained motion systems.

• Single‑stage strain wave design achieves reduction ratios up to 200:1, eliminating multi‑stage complexity
• Zero backlash for life supports highly repeatable and accurate positioning
• Precision motion performance with repeatability to ±10 arc‑sec and positional accuracy to ±90 arc‑sec
• Multiple teeth share load simultaneously, enabling high torque density in a compact footprint
• Pre‑lubricated for life, eliminating maintenance and relubrication intervals
• Low operating noise and reduced heat generation support continuous‑duty applications
• Wide ambient temperature capability from ‑40°C to 90°C
• Rated IP64 for protection against dust and splashing water
• Designed to integrate with SureServo and SureStep motor platforms

Precision servo gearboxes are available in multiple form factors to support high‑performance motion control across a wide range of machine layouts.

• Offered in in‑line shaft, right‑angle shaft, and hub‑style in‑line configurations
• Helical‑cut planetary gearing models deliver smooth torque transmission and reduced vibration
• Maintenance‑free grease fill eliminates service intervals over the gearbox life

Timing belts and pulleys allow adjustment of speed and torque while connecting mechanically rotating components. Timing (toothed) belts and timing pulleys are availble in MXL, XL, L, 5M, and 8M styles.

Drive couplings are power transmission components used to couple the shafts of various mechanical devices, and to compensate for shaft misalignment, reducing stress on shafts and bearings. Jaw, double loop, Oldham, servo-application, advanced disc, and high torque disc couplings are available.
