Large Bearings-Bore Size 50mm 2in and larger These bearings are not easily pressed on a shaft, and should therefore be heated using an induction heater, hot plate or temperature controlled oven. Do not wash out the protective coating.

The machine can then be correctly positioned according to the calculated live va lues provided on the display. For spherical roller bearings with W33 or E suffix groove in outer ring and three lubricating holes spaced at the center lubricating fitting must be used.

The bearing must be on supports to isolate it from direct contact with bottom of the tank, thereby preventing the possibility of localized overheating which could result in bearing damage.

The other halves of the seals are inserted in the cap and the space between the lips of the seals filled with grease. After attaching the measuring units to the shafts the on-screen instructions guide you simply through the alignment prcedure. These pillow blocks can also be supplied in cast steel.

If necessary tighten the locknut to a point where interchangeable. Lubricate the surfaces that slide against each other during tightening. To adjust labyrinth seal flingers, move the flingers axially toward housing until they contact insert. The housing base is checked for alignment, ensuring that the housing is within acceptable limits, and the mounting bolts are then slightly tightened.

Mounted in seconds, SKF SYSTEM 24 provides constant lubrication at a predetermin ed rate to minimize downtime and reduce caatalogo costs of expensive manual maintenance procedures. SKF Bearing heaters are powerful, safe and have excellent long-term reliability.

Turn the nut with a hook spanner according to the illustration. Apply a coat of light oil to the shaft and bearing bore. EasyPull dismounts the most difficult bearings Dismounting a bearing can be a demanding task for both user and puller. If a catalpgo rubbing seal is selected, care must be taken with regard to the surface finish of the shaft.

Blocks If the bearing is to be held locatedfixing rings are inserted between the side faces of the outer ring and the housing shoulders. When the locknut has been tightened to achieve this, then insert and tighten cap screws. It should also be noted that bearings are generally lubricated after mounting. Also certain operating conditions i. The maximum permissible misalignment of the shaft is approximately 1 up to shaft diameters of mm 3.

SNL SNH pillow blocks of cast iron with either self-aligning double roll ball bearing for normal loads or self-aligning spherical roller bearing for heavy loads.

The housing cap is filled and the cap bolts tightened to the recommended torque, see Table on Pages 26 through It is recommended that the shaft surface roughness does not exceed RMS t: Tighten the nut just enough to ensure that the bearing and shaft make contact with the sleeve, but do not tighten to drive the bearing further up the sleeve.

Can be temporarily deactivated Reduced inventory cost as one lubricator covers all time settings. To recognize A-design, cap of Series: Note how much the locknut will have to be The unmounted clearance of each bearing must be tightened for the holes in the locknut to align with the holes measured and recorded.

Less wear on belt and pulley Less friction and therefore lower energy consumption Less vibration and noise Increased safety-prevents belt turnover in the pulley Increased up time Lower costs Advantages: High accuracy but simple to operate The TMEA 1 alignment tool uses two measuring units, both provided with a laser d iode and a positioning detector.

The maximum permissible misalignment of the shaft is approximately 1. Double-lip seals are designated TSN followed by the housing number and suffix G, ie. When oil is used, it is advisable to employ an oil reservoir or an adequate supply of oil and effective housing seals so that the oil does not leak out. Dispense rate setting is a simple part of the installation process. One labyrinth seal is placed on the shaft.

Then oil should be used. A verysmall movement of the nut will usually align a tab with a slot. Slide one labyrinth seal, catalobo of labyrinth flinger, with prongs towards bearing location and labyrinth insert with O-ring installed on its O.

It s as easy as that. Tighten the set screws.

For greasing quantities, refer to Page The housing base is placed in position and the mounting bolts loosely fitted. The split design simplifies mounting. At the initial start up, with shaft rotating, lubricate seals through grease fitting until a bead of grease appears around the periphery of the flingers. Home Documents Catalogo Chumaceras Skf. V-ring seals may be used for oil lubrication. At temperatures over 70C, the lubricating intervals should be halved for each 15C ris e, but the maximum permissible operating temperature for the grease should obviously not to be exceeded.

The laser position indicates the nature of misalignment allowing easy, accurate adjustment Facilitates simultaneous adjustment of tension and alignment V-guides allow for alignment of a wide range of V-belt pulleys The unique dual laser eliminates need for mirrors or reflectors, minimising diffusion of the beam over longer distances.

Pillow block housings caps can be equipped with grease fittings. The maximum permissible misalignment between shaft and housing must be restricted to 0. In such cases the most important during this and subsequent operations, that bearings should be washed and dried to prevent any the shaft be blocked up so the bearing is unloaded.

Fit a clean tube with one end squared and bore slightly larger than the bearing bore, against the bearing inner ring. Canadian designed heavy duty pillow block is made of ductile iron to complement the well proven SD design. Only where, after mounting, an even distribution of grease in the bearing is not possible should one consider greasing prior to mounting. The relubrication intervals hours of operation obtained from Diagram A are valid for bearings in stationar y machines where loading conditions are normal.
