SKF has unveiled a trio of new seal profiles for its SNL plummer block housings. For distributors and end-users an efficient and cost-effective means for their production has also been introduced.
The latest SKF seals have been developed for applications where better sealing performance is required than that provided by a labyrinth seal, but where space does not allow for a taconite seal. The new seal profiles are: TX, a single acting design with a lip seal facing outwards that prevents the ingress of contaminants while enabling grease flushing; TY, a double acting design with a lip facing outwards and a lip facing inwards; TZ, a double acting solution that features two single-lip seals in a back-to-back configuration.
Spherical roller bearings from Schaeffler now even more durable • Rollers with end profiling will be successively introduced in all 241-series spherical roller bearings with bore diameters of 500 mm and above.
• Edge pressure caused by abrasive material wear is at least 20 per cent lower.
• Their use in roller presses – which are primarily used as grinding mills for cement and raw materials but also find use in the mining industry – offers lots of potential.
Bearings are circular, much like the economy they are used in. As more customers avoid disposing of bearings needlessly, Chris Johnson, managing director of bearing re-lubricator SMB Bearings, explains the sudden surge in popularity of reusing and recycling ball bearings through relubrication. 
The reliability of most rotating equipment is almost inevitably linked directly to bearing life, and it is estimated bearing failure is responsible for almost 21% of these equipment failures (Bloch, 2011). 
Save your bearings with LabTecta®66, which can reduce bearing oil contamination from 83% to 0.0003%.
By offering a wide choice of materials and heat treatments for rolling bearings, performance and operating life can be optimised, even for the most demanding industrial applications, says Dr Steve Lacey, Engineering Manager at Schaeffler UK.
