The pre-lubricated be-arings will save assembly time by eliminating the need to grease thebearings. Due to factory calibratedgrease fill, the reliability of the be-aring will be improved. Using pre-lu-bricated bearings will reduce main-tenance costs as Linear ball bearings and unitsfor shaft diameter 6 mm and greaterare factory pre-lubricated1)by de-fault2). Due to the integrated greasereservoir and the use of SKF double-lip seals (2LS), most applications willnot require relubrication because thetheoretical relubrication interval ex-ceeds the bearing Linear bearings are lubricatedwith the high-performance SKFgrease technical support as well asthe technical handbook for linearbearings and units (order number6402 EN or download at ) are available forfurther questions on the factory double-lip seal ensures main-tenance-free life for pre-lubricatedbearings that operate under stan-dard conditions.

3 The integral seal hasbeen designed specifically for linearbearings. The seal lips maintain fullcontact with the shaft while offeringa superior sealing solution evenwhen used with the shaft for theself-aligning Linear bearings of theLBC series. The seals have also beenoptimized for low friction operation. LubricantLGEP2 is an extreme pressure be-aring grease from SKF for a widerange of industrial and automotiveapplications. Based on a lithium soap/mineral oil, the additives provi-de a good corrosion resistance andanti-wear protection.

Thebearing conforms to dimension se-ries 1 according to ISO 10285. The LBBR raceway segments ha-ve been designed to fully utilize theentire length of the load zone to in-crease bearing capacity and extendbearing service life. The plastic cage has been rede-signed to provide optimum perfor-mance. All ball recirculations are de-signed to offer no resistance to thecage on the running-in and runoutStainless steel variantLBBR Linear ball bearings are alsoavailable with stainless steel balls andraceways for wet or corrosive envi-ronments.

9 The stainless steel variantis identified by a HV6 suffix in the de-signation, LBBR 16-2 used in combination with SKFstainless steel shafts, it is possible tocreate a guidance system made enti-rely of stainless the recirculation. The redesignedcage also accommodates larger ballsto provide increased load capacityand service life. The sealed variant is fitted withintegral double lip seals. These sealshave an inner lip to keep lubricant inthe bearing ; the outer lip acts like awiper seal to keep contaminants outof the bearings are fitted withnon-contacting shields to protect thebearing from large contaminant par-ticles. LBBR Linear ball bearings donot need to be secured axially in thehousing provided the housing bore issized correctly.
