Unior centering chair for professional use
Professional centering chair Unior.
Evolution born from cooperation with professional mechanics. We have redesigned many of its functions. The base has been made stronger for better accuracy and we've also added magnetic tapered universal fixed axis adapters that can be stored anywhere on the base. The arms are longer to better accommodate a 29+ wheel and the jaws are widened accordingly. All threads, springs and bearings have been revised, resulting in smoother operation and less frequent calibration. In addition, we offer high gloss white stickers that you can use on the base and arm of the jaws to enhance the contrast of the background, making it significantly easier to use.
Improvement:
- Stronger base for better accuracy.
- Longer and refined upright arms for better 29+ wheel clearance and true precision.
- Wider jaws for more clearance in 29+ wheels.
- Accommodates wider axles, works with hubs for through axles up to 197 mm wide (including the use of adapters). Max. spread of arms 230 mm (without using adapters).
- New bearings at the base of the upright arm adjustment are preloaded for better accuracy and reduced calibration frequency.
- Refined jaw tips for easier radial alignment.
- Adjusted threads and springs for smoother operation.
- 8mm counter top mounting holes at bottom, 268mm center to center.
- Smoother design, all black.
- Comes with tapered magnetic axle adapters - one size fits all (12, 15 and 20). The adapters are now magnetic and can be attached anywhere on the base. Contains a screw for more permanent fixation on upright arms.
- Includes high gloss white stickers that cover the base and arm of the jaws for better background contrast (the stickers are not pre-applied).
Compatibility:
- Accommodates wheels from 16 to 29+ inches with or without tires.
- Supports fixed, quick-release and thru-axle hubs.
- Thru-axle hubs are attached using adapters (part of the stand).
- One pair of thru-axle adapters supports all thru-axle sizes.
Standard features (same as the previous model):
- The geometry of the jaws allows simultaneous axial control for precise alignment of the rim.
- The jaws have plastic coated tips to prevent scratching the rim.
- The upright position of the arms can be adjusted using the adjustment knob to match the width of the axle. The position of the jaw arm can be adjusted to match the radius of the wheel and the distance of the jaw tip can be adjusted according to the width of the rim.
- When changing a wheel, the pre-tensioned upright arms and jaw arm can be quickly pulled away and automatically spring back to the set position when a new wheel is inserted. This allows for faster centering of several wheels of the same size.
