Sealmaster Mounted Roller Bearings - SealMaster - #9

Text version of the page

102 MOUNTED ROLLER BEARINGS • Consists of an elastomeric rubber sealing element bonded to a steel shield. • Functions well in wet and dirty environments up to 250° F. • Has good chemical resistance properties. • Race mounted seals are not subject to misalignment distortion. • Shields are black oxide treated for corrosion protection. • Each collar has 2 setscrews spaced at 120° - provides balanced three-point contact and symmetrical locking. • Hardened setscrews in a soft collar provide maximum holding power in applications involving heavy loads, reversing and vibration... a special coating on the setscrews reduces the friction when inserting and torquing them into the lock collars, resulting in more holding power. • Double extended inner races provide excellent shaft support - load is distributed evenly over a wide area. • Collars also serve as 2 extra flingers that rotate with the shaft to repel contaminants away from the seal. • Black oxide treated for added corrosion protection. SINGLE LIP RACE MOUNTED CONTACT SEALS Available on all bearing sizes recommended where moisture conditions prevail... 1. SINGLE LOCKING COLLARS Generally for applications involving shaft length considerations or limited space. • Available from stock in bore sizes, 1 3/4" - 3 15/16". • Designated with "A" suffix, e.g. RPBA207-2... see pages 105, 108, 109, 115, 117, and 120. 2. CYLINDRICAL CARTRIDGE INSERTS Designed to mount directly into customer housings and as inserts in expansion RPB housings. • Available from stock in 1 3/4" - 5" bore sizes with felt and contact seals. • High temperature grease and seals can be supplied on request. 3. EXPANSION TWO AND FOUR BOLT PILLOW BLOCKS • Available from stock in bore sizes 1 3/4" - 5". • Total expansion 3/16" - 3/8"... see pages 106, 109 and 111. 4. CAST STEEL PILLOW BLOCKS For applications requiring greater housing strength than cast iron. • Two bolt bases - bore sizes 1 1/2" - 3 1/2"... see page 112. • Four bolt bases - bore sizes 3 15/16" - 5"... see page 112. 5. INDUSTRY INTERCHANGEABILITY • Same bolt centers and base-to-shaft centerline as most competitive one-piece housings. (Metal nameplate attached securely beneath the grease fitting for long-lasting identification.) • Longer bolt slots permit easy replacement for most competitive brands. • New RPBXT Series has interchangeable shaft-to-centerline dimensions and bolt hole spacing with the popular 500 Series SAF style spherical roller bearing pillow blocks... see pages 110 and 111.
