ROX. Born for the dust.
The spherical roller bearing built to survive quarries, cement plants and the toughest heavy-industrial environments; with more than double the bearing life of a standard design. Now available at Signet.
When dust cuts bearing life short, ROX keeps you running
In quarries, cement plants and on heavy-duty conveyors, dust and debris are the biggest threat to bearing life. Standard seals struggle to keep contamination out, leading to premature failure, unplanned downtime and repeat maintenance costs.
ROX is the world's only spherical roller bearing with dual metallic deflectors, engineered by SNR (a brand of NTN Group) specifically to thrive in these conditions. Signet supplies the full ROX range as an authorised NTN‑ SNR distributor, backed by our own technical support.
Built for conditions that wear standard bearings out early
More than 2x longer bearing life
Dual metallic deflectors block dust and debris that standard seals let through, extending service life well beyond a standard bearing.
100% compatible with standard premium bearings (ISO)
A drop-in replacement for your existing ISO-standard bearings — no redesign and no compromise on fit.
Lubrication reduced by more than 50%*
*Proven by NTN‑SNR customers. Less frequent lubrication means less maintenance time and lower running costs.
How ROX brings you peace of mind
- ✓Dust and debris blocked by metallic deflectors (ZZ)
- ✓Shock resistance improved by a nitrided cage
- ✓No friction — deflectors don't contact the outer ring
- ✓Fits directly inside SNC plummer blocks (standard sleeves and locating rings included)
- ✓Clearance checking with standard feeler gauges — no special tools
- ✓Handles misalignment up to 2°
- ✓Operates across a -40°C to +200°C range
80% faster bearing dismounting with MagicSleeve
Pair ROX with SNR's MagicSleeve innovation to simplify dismounting. What used to take around 25 minutes can take less than 5 — no hammer, grinder or torch required.
Second nut on the opposite side for smooth removal
Same wrench used for mounting
Safer, faster and easier maintenance
Standard sleeve
Simple effect → mounting only.
MagicSleeve
Double effect → same mounting speed, up to 5x faster dismounting.
What could ROX mean for your operation?
NTN‑SNR modelled the potential impact of switching to ROX for a mid-sized quarry. Every site is different, but it gives a sense of scale.
| Setup | Maintenance / year | Bearings / year | Maintenance (hours) | Production gain (hours) | Turnover gain |
|---|---|---|---|---|---|
| Standard | 2 | 40 | 80 | 1,760 | €4.5m (baseline) |
| ROX | 1 | 20 | 40 (−5 days) | 1,800 (+2.3%) | €4.6m (+€100,000) |
| ROX + MagicSleeve | 1 | 20 | 32 (−6 days) | 1,808 (+2.7%) | €4.622m (+€122,000) |
