Whether the device of NSK bearing can be correct; affects the accuracy, life and function. Therefore, the device for drawing and assembling part of the bearing should be fully studied. It is expected to be installed according to the operating specifications. The items of operation specifications are generally as follows: (1) Clearing the bearing And the bearing dry parts NSK bearing device can be correct; affect the accuracy, life, function. Therefore; depict and assemble some of the bearing device (2) to view the dimensions of the dry components and finishing conditions (3) device (4) View after installing the bearing (5) Supply smoothing agent; Expect to be in front of the device; just open the bearing package. Generally smooth grease is smooth; not cleaned; directly filled with smooth grease. Smooth oil smooth; generally do not need to be cleaned; Use or high-speed bearings; wash with clean oil; remove the rust inhibitor applied to the bearing. Remove the bearing of the rust inhibitor; easy to rust; so can not be placed regardless. Again; has been sealed into smooth Grease bearing; does not clear the direct use.
NSK bearing device method; due to bearing layout, cooperation, conditions; general; because most of the shaft rotation; so the inner ring demand interference cooperation. Cylindrical hole bearing; multi-use presses; or more hot-packing method. Cone hole Occasionally; directly on the taper shaft; or with a sleeve device. When the device is attached to the outer casing; generally the clearance cooperation is more; the outer ring has an interference; the press is generally pressed; or there is also the cold shrink cooperation of the device after cooling. Method. Use dry ice as the coolant; cold shrinkage cooperation device; the moisture in the air will condense on the outer surface of the bearing. Therefore; the appropriate anti-rust method.
When viewing or replacing parts regularly; the bearings need to be dismantled. Generally, the shafts and bearing boxes must be used continuously; the bearings are often used continuously. Therefore, the layout should be considered when the bearings are dismantled; the bearings, shafts and bearings are not damaged. Boxes and other parts; together with the appropriate disassembly of the things. When disassembling the static cooperation ferrule; only pull the force on the ferrule; do not pull the ferrule through the tumbling body.

U Shaped Nails

U Nails

U nails refer to a kind of fasteners with two-pronged shanks. These U nails are usually used for attaching the mesh fences to wooden posts and frame, hence the name fencing staples. These practical nails can fix the wire, rope even Barbed Wire to the ground, wooden post or stakes. Therefore, people like to use them in agriculture & gardening, viticulture & other fruit growing, animal coops & plant trellises construction.
