The Grip chain is designed for vertical conveyors where the items are conveyed between two uni Grip links. The uni Grip is a 1873 chain supplied with moulded rubber inserts.
The main application for Grip 1873-G4 is vertical conveying of cans or bottles.
The flights for the 1873-G4 chain are the Snap-On type. The Grip chains have a 0.75 in. pitch side flexing roller base chain.
The recommended temperature area for the Grip chain is -40 to +80°C (-40 to +176°F).

Rellwin has a wide variety of Plate Top and Gripper chains.The roller chain based Plate Top is developed for greater loading capacity and permits even higher speeds and longer runs than tabletop chains. The roller chain based Gripper is perfect for product elevating, 

lowering,rinsing, sterilizing and inverting,by means of soft rubber gripper elements. The base chain is made of stainless steel.
843-,963-,1873-series,with"snap-on"plastic top plates combine the benefits of a plastic conveying surface with those of a precision roller base chain:

less slip- stick,high working load and accurate positioning.
Main applications of Gripper chains can be found in glass works.However,they can be used in various other situations, such as crate handing and can

 manufacturing.The grippers are provided in 3-or 4-finger grippers for smaller products and in D-type Grippers for other applications.

POM: That generic polyethylene oxide (abbreviated POM), also known as Race Steel, Special Steel. It is  Based on such as formaldehyde as raw material

 to aggregate income,POM-H (polyoxymethylene homopolymer), POM-K (polyoxymethylene copolymer) is a thermoplastic plastic high 

density, high crystallinity. Has good physical, mechanical and chemical properties, especially those with excellent abrasion performance. 

Feature:

1,POM has a very low coefficient of friction and good geometric stability, particularly suitable for the production of gears and bearings

2.High temperature properties,and therefore is also used pipe device (pipe valves,pump housing), lawn equipment, etc

3,Is a tough elastic material, even at low temperatures are still very good creep properties, geometric stability and impact resistance

4,High crystallinity of POM cause it has a high shrinkage rate, reaching a high of 2% to 3.5%. For a variety of enhanced materials have different shrinkage

5.POM is a crystalline plastic, melting point clear, once they reach the melting point, melt viscosity decreased rapidly. 
Specific gravity 1.43, melting point 

175 ° C, tensile strength (yield) 70MPa, elongation (yield) 15%, (break) of 15%, the impact strength (notched) 108KJ/m2, (band gap) 7.6KJ/m2
