Drive Configuration

| ||
| Gearing Configuration | |||
| Your choices are... | |||
| Straight Tooth | Straight tooth gears contain teeth that run parallel to the axis of the gear. Load movement or transfer is manual or walk-behind. | ||
| Helical Tooth | Helical tooth gears provide continuous engagement along the tooth length and are often quieter and more efficient than straight tooth gears. | ||
| Roller Pinion | Roller pinion drives use bearing supported rollers that mesh with the teeth of that rack in order to provide minimal to no backlash. | ||

| |||
| AGMA Quality Rating | The American Gear Manufacturers Association (AGMA) publishes quality-level standards for gears based on pitch variation, profile error, and tooth alignment accuracy. Quality levels are defined in the AGMA 2000-A88 Gear Classification and Inspection Hand Book. In general, higher quality levels indicate higher quality gears. AGMA 8 and 9 describe lapped gear teeth. AGMA 11 and higher describe hardened and ground teeth. Typically, AGMA quality requirements involve application consultation with suppliers. | ||
| Your choices are... | |||
| AGMA 8 | Devices have an AGMA 8 quality rating. | ||
| AGMA 9 | Devices have an AGMA 9 quality rating. | ||
| AGMA 10 | Devices have an AGMA 10 quality rating. | ||
| AGMA 11 | Devices have an AGMA 11 quality rating. | ||
| AGMA 12 | Devices have an AGMA 12 quality rating. | ||
| Other | Other unlisted AGMA quality rating. | ||

System Parameters

|
| ||
| Axis Drive Force | Axis drive force is the maximum drive force for which drives are rated. The rating represents the torque of the motor transmitted through the pinion to the rack. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Axis Weight Rating | Axis weight rating is the rated weight for the driven axis. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Preload | |||
| Your choices are... | |||
| Split Pinion | Split pinions contain a torsion spring or other anti-backlash mechanism that enable the pinion to load both sides of the rack simultaneously. | ||
| Mechanical Preload | Mechanical preloading consists of a drive pinion and a second preload pinion and gearbox. To maintain preloading and eliminate backlash, the preload assembly applies an opposing force to the drive assembly. | ||
| Electrical Preload | Electrical preloading consists of a drive pinion and motor, as well as a second pinion/motor assembly that applies an opposing or braking force. The opposing motor can take over during deceleration, smoothing carriage stops and reversals. | ||
| Other | Other unlisted or specialized preloading system. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
|
| ||
| Integral Rack and Rail | Rack teeth are machined or ground directly onto the moving element to increase power transmission efficiency. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Ground Teeth | The gearing (rack and pinion) features hardened and ground teeth for a precise fit and smoother operation. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
