SKF insert bearing units UC range

1 SKF insert bearing unitsUC rangeApplications include Parcel and baggage handling conveyors Material handling conveyors Food process machinery Packaging equipment HVAC equipment Agriculture machinery Construction machinery Textile machinery Fitness equipment Escalators Metals industrySKF UC range , designed for JIS* equipmentYou need a robust and reliable insert bearing unit solution, one that s easy to install, simple to order and improves productivity. SKF now offers a product that matches your operational and appli-cation requirements. At SKF, we have developed a range of insert bearing units , called UC range , designed to be interchangeable with JIS* equipment. These SKF UC bearing units are designed with a set screw locking feature, to operate in environments where systemic vibrations are characteristic application conditions. Easy to order, easy to replaceYou want a solution that makes your life easy A solution with the same boundary dimensions, housing conigurations and part numbers as many other products available today on the market.

2 The SKF insert bearing units - UC range achieves this and more. It s an interchangeable solution with JIS* housings available today on the market with an enhanced locking design insert bearing that helps pro-vide more productive, more reliable, and smoother running rotating equipment. What s more, no modiication of your machine is needed. The dimensions meet most of the current UC designated bearing unit it-ting requirements, enhancing interchangeability. And whatever prod-uct you need, with SKF you know it will be easy to obtain and straight-forward to install.* JIS: Japanese Industrial StandardsUP TO16%BETTER HOLDING POWER ON SHAFTSC ombining JIS* compatibility with SKF reliabilityWith over 100 years of experience, SKF understands machine and plant productivity and the need to deliver high rotating equip-ment performance. The SKF UC range has been designed to provide reliable performance as well and reduce machine downtime. It includes speciic features that can make the difference in your enhanced set screw locking system One of the reasons for failure in a low speed, highly loaded conveyor applications is machine vibration loosening the locking systems.

3 SKF has overcome this problem by using an enhanced set screw locking design. At its heart is a nylon patch that creates extra resist-ance to screw loosening. A simple, solution which eliminates the labour associated with the use of messy liquid locking compounds that have no removal or reinstallation options. The locking device on the SKF UC range increases the axial holding power by up to 16% ( Diagram 1), so there is greater grip between the shaft and bearing . This is a big advantage for units operating in systemic vibrating applications, such as conveyors. A solid base and solid feet for increased cleanliness and better bearing unit supportThe solid base design of SKF insert bearing units UC range provides a cleaner surface with less contaminant ingress for improved bearing unit support, especially the often heavily contaminated conveyor operating environment. A solid base design is now standard on our two bolt langed housings as well as a solid feet on our pillow block hous-ings ( ig.)

SKF offers these end cov-ers as high availability option. SKF high-quality greasePoor lubrication accounts for over 36% of pre-mature bearing failures. In fact, most low speed applications fail due to lubrication related issues, not necessarily due to bearing fatigue. Provided recommended maintenance intervals are followed, SKF high-quality grease helps bearings achieve expected service life as the SKF range of lubricants are designed to per- form under real conditions ( Table 1).

5 Sealing systemThe standard seal for SKF insert bearing units UC range is the rugged integral seal pro-tected with an additional linger to help exclude contaminants. The integral seal con-sists of a pressed sheet steel washer with a sealing lip made of NBR bonded to its inner surface. The coated non-contact sheet steel washer forms a narrow gap with the cylindri-cal surface of the inner ring protecting the land-riding seal against contaminants. Enhancing the seal s effectiveness are exter-nally applied coated sealing solutions are available for extremely contaminated operating environ-ments.
