Dual Lead Adjustment
Renold’s dual lead adjustment capability is designed to make backlash setting faster, simpler and more practical for precision machinery. This is especially valuable for equipment where downtime is costly and where backlash must be controlled without extensive disassembly.
The Renold Ren-Adjust dual lead adjustment mechanism is used with dual lead gear sets in positional machinery requiring a high degree of accuracy, such as rotary tables and machine tools. It allows precise backlash adjustment while helping reduce the time required to carry out maintenance or setting work.
Simple, precise backlash adjustment
With a dual lead worm gear, backlash is adjusted by moving the worm shaft axially. The Ren-Adjust mechanism is designed to make this process easier for maintenance teams and machine builders.
In a typical adjustment process, the shrink disc is removed so the worm shaft can move independently from the adjustment sleeve. Turning the captive screw then moves the dual lead worm shaft axially, changing the working backlash. Once the backlash is set to the required level, the shrink disc is reapplied.
This design can help reduce downtime because adjustment can be carried out without removing the worm shaft or draining the oil in suitable installations.
Ren-Adjust has been designed as a simple replacement for existing machinery and may also be specified by machine tool and rotary table manufacturers as a like-for-like component. In many cases, it can be used without major redesign or modification, making it a practical choice for OEMs and operators looking to upgrade or replace existing adjustment systems.
Key benefits

- Reduced downtime: Adjustment can be carried out efficiently in suitable systems.
- No worm shaft removal: Helps simplify maintenance procedures.
- No oil draining required: Supports cleaner, quicker adjustment where applicable.
- Suitable for precision machinery: Developed for positional applications such as rotary tables and machine tools.
- Replacement-friendly design: Can support OEM integration and equipment replacement requirements.
Product specification considerations
Because Renold loose worm gears can be supplied for a wide range of duties, the correct specification depends on the machine and operating environment. When enquiring, it is helpful to provide as much information as possible so the Renold team can assist with selection or quotation.
Useful details include:
- Worm and worm wheel dimensions
- Centre distance
- Ratio or number of starts
- Direction of rotation
- Required backlash or adjustment range
- Torque, speed and duty cycle
- Material or heat treatment requirements, if known
- Existing drawings, part numbers or worn samples
- Lubrication method and operating environment
- Required accuracy grade or inspection documentation
- Whether the gear set is for replacement, repair, upgrade or new equipment
If you are unsure which information is available, Renold can still help you begin the enquiry process. For replacement projects, drawings or worn components may assist with identifying the correct worm gear design.
