The force applied during the assembly and disassembly of the bearing should focus on the following key points:
(1) The combined force of the force can pass through the axis of the bearing; this requires that the point of application of the force is uniformly symmetrical and stable; the force is applied through the spherical surface or parallel to the axis.
(2) The size of the force should be smooth and uniform; it should not be impacted; this requires the use of oil pressure or something that can apply a smooth tension or pressure; the real has to use hammering; also through the copper sleeve and other soft Do not use the metal to cushion; the tapping force can be light. The best use of copper rods or copper hammers for hammering.
(3) Prevent the force from being applied through the rolling body; this requires the inner ring to apply force when the inner ring (shaft ring) is assembled and disassembled; the outer ring is applied when the outer ring is assembled and removed.
(4) The drag force should continue to the extent it should be; for example, when the bearing is installed, the force should be stopped when the bearing is just loaded to the correct orientation; ensure that the end face of the ferrule (gasket) abuts against the shoulder hole or the shoulder end face of the shaft; Can't be squeezed too tightly;

Eyelet Dies

Zonglan Hand Tools for eyelets consist of piercing and attaching hand toolsets.

This manual set is designed to be used with a hide face mallet. It is good for piercing material and attaching curtain eyelets afterward. Not all hand tools are the same and it is not easy to find such a highly qualified hand tool for attaching curtain eyelets in today`s world.

Though these tools are designed for low-volume eyelet application projects, Zonglan Hand Tools are professionally designed and produced with advanced technology for decades of problem-free use. Zonglan Hand Tools are made of Stainless Steel to increase their resistance to oxidation. Their surface is specially treated for metal hardening for stronger durability against harsh hammer usage.

Zonglan Hand Tools are designed in such a manner affording the use of minimum force with maximum comfort. In addition, thanks to its precision, the eyelet application quality of Zonglan Hand Tools is far better than the application quality of its ordinary competitors.

Our hand tools sets are available for 6mm,10mm and 12mm Easy Apply Zonglan eyelets and are suitable to attach them onto various substrates, including tarpaulin, drapery and home textile.
