If F&F bearings after dismantling the again want to use, it can never through pressure roller remove force. Separation of the type of bearings with rolling body and maintains a combination of bearing a with another circle can dismantle circle respectively. The separation of type bearings, has a loose with a circle of bearing should be removed from the first seat. Has the interference fit of bearing circle but according to bearing type and size, use the following introduces tools and accessories to remove.

1. F&F cylindrical hole bearings

Use hammer tap bearing laps, or use it will shake handshandle small bearing removed from seat. The shake handshandle claw discs removed should be kept in the loop or bearing on adjacent components. The interference fit installation large bearings, generally require greater force to remove, especially when a friction and work has produced corrosion. In this case, the use of hydraulic method can greatly simplified remove work, of course, must have the necessary in the configuration of oil and grease groove way when can do that. Remove not raised edge or take only one side with raised edge of cylindrical roller bearing (NU, NJ and NUP design), can use a special electricity heater, the heater is rapid heating inner ring and axle temperature won't rise, so the inner ring inflation, it is easy to tear down. Inner circle heating and tear down later, in addition to. If you need to install and remove the same often size bearings (such as car-body bearing or rolling mill bearing), use the electricity tools will be very economic removed. NU, NJ and NUP design of cylindrical roller bearing inner circle, if only occasionally remove, or down to the inner ring of larger diameter, can use hot shirk ring (also called heating ring), and economy, it is convenient, detachable inner circle is about as high as 400 mm diameter. Hot shirk ring can be used electric heat plate, heating coil or open flame heated to 200 to 220 degrees, and then put on inner ring and handle clamping. In order to heat

Good sex, bearing inner circle first with antioxidant viscous oil.

2, F&F tapered bearings in the hole

Packed in tight set to cover on the bearings, can mix nut loose a few laps, then with an awl or tubular back Ao set or special wedge block remove, just in bearing inner circle knock several can remove. Remove the back cover on the discharge of bearing, should be removed bearing locked tight device (shaft nut, cover, etc), the threads in set screw on the back discharge nut, screw up until set of loosen. If set out on the shaft threads or shaft shoulder, but on a hole into thick wall support circle as far as possible, in order to prevent the sleeve deformation and nut tightening the damage to thread. If something to open in cone shaft neck, tight or a set back a large bearings of discharge, the hydraulic nuts or hydraulic method, would be very convenient. In the face of the hydraulic oil injection with, bearing will stand
And that is a separation. Therefore, it is necessary to provide some form of the dynamic device, such as axis nuts or end plate to limit bearing axial to escape.
