MountingCollar-mounted roller bearing units slide easilyonto the shaft and are locked in place with atwo set screw locking collar. The locking collarkeeps pressure on the set screws helping tomaintain the tight fit with the shaft. For addedholding power, the largest sizes are designedwith two locking collars, indicated in thedimension tables. Mounting is quick and easy.

HousingsThere are a variety of housing styles in the SKFroller bearing unit product line, including pillowblocks, flange units and take–ups. Pillow blocksare made in two configurations: the SYE isdimensionally interchangeable with competitor"E" designs and the SYR is dimensionallyinterchangeable with units such as the DodgeS–2000, Linkbelt P–B22400, and Rexnord ZA2000 series.

MountingThe ConCentra roller bearing unit uses apatented multi–tapered sleeve arrangement,making it easy to mount the bearing to theshaft. This method provides nearly 360° ofinterference fit, which does not offset the centerline of the shaft and helps reduce fretting.

HousingsThere are a variety of housing styles in theConCentra roller bearing unit product lineincluding pillow blocks and take-ups. Pillowblocks are made in three configurations: the SYEis dimensionally interchangeable with competitor"E" designs, the SYR is dimensionallyinterchangeable with units such as the DodgeS–2000, Linkbelt P–B22400, and SKF collar-mounted unit roller bearings; and the SYT isdimensionally interchangeable with plummerblock assemblies of series SNL 5.

Introduction

ConCentra roller bearing units are suppliedcompletely assembled with bearings, seals, andgrease. They are ready for installation right outof the box and require no internal adjustment.

ConCentra units can be used in the sameapplications as collar-mounted roller bearingunits. The difference between the two types isthat the ConCentra unit mounts with a near360° interference fit (see "Mounting", to theright, and Product descriptions on followingpage).

BearingsThe bearings used in ConCentra roller bearingunits are based on the high capacity SKF 22200series spherical roller bearing. They can handleheavy radial and axial loads, running and staticmisalignment, and high operating temperatures.Clearances in the bearing are preset; noadjustment is required during mounting.

GreaseAll roller bearing units are factory lubricatedwith SKF LGEP2 grease or equivalent.

TolerancesIn normal cases shafts machined to tolerance h9can be used. The cylindricity as defined in ISO1101:1996 should be according to IT5/2. Forless demanding applications h10 and IT7/2 maybe satisfactory.

SKF roller bearing units are available in avariety of housing styles and two mountingmethods. These units are simple and economicbearing arrangements combining the high loadcapacity and self-aligning features of the SKFspherical roller bearing with the convenience ofset screw mounting and a rugged cast-ironhousing. They come pre-greased and fullyassembled. Installation time is reduced andthere is no risk of bearing contamination duringassembly. Roller bearing units can accommodaterunning or static misalignment of ±11⁄2° and can be supplied as free or held assemblies. Allunits incorporate triple protection TriGard sealsas standard, but can also be supplied withoptional seals.

Collar-mounted units use a locking collardesign to firmly secure the bearing inner ring tothe shaft. The two set screws extended throughthe inner ring of the bearing and lock into theshaft. The elasticity of the locking collarsmaintains pressure on the set screws helping tomaintain a secure fit to the shaft even in severepower transmission applications. Mounting isquick and easy. Slide the unit on the shaft, boltthe housing securely to the mounting surfaceand tighten the two set screws.

ConCentra units combine the advantages ofadapter mounting found in split pillow blockswith the convenience of set screw mountingfound in collar mounted roller bearing units. Theresult is a positive, near 360° interference fitwith the shaft. This is achieved with a uniquepatented multi-tapered sleeve arrangementdeveloped by SKF. The shaft is held concentric tothe bore of the bearing resulting in reducedfretting corrosion, good balance and lowvibration. Dismounting is just as easy. Loosen themounting set screws and tighten thedismounting set screws until the multi-taperedsleeve releases its grip, usually with a “POP”. Noneed for cutting torches or other mechanicaldevices. Downtime and shafting cost are saved.

ConCentra units are available inSYE-N, FSYE-N, SYR-N, and SYT (metric) pillowblocks as well as TBR-N and TRH-N take-uphousings. FYR and FYRP flange housing areavailable on an application review basis. This isdue to the often limited access to thedismounting set screws.
