200 series

202, 205, and 260 in transparent casings are the standard grease dispensers for use on most bearing points. As they only deliver grease when the bearing is in operation, the bearing is equally protected from over-lubrication and dry running.

  • The devices are supplied with a 'medium' strength spring.
    Each pack of 10 comes complete with three 'weak' and three 'strong' springs for easy installation when needed.
  • the 260 model is supplied in a single pack with additional springs (weak and strong)
  • Operating range: -25 to +120°C

Choose the right unit

a) Size of the unit
 

The following four factors must be considered when selecting the size:

  • Shaft diameter
  • Whether the bearing is open or enclosed
  • Peripheral speed of the shaft
  • Whether interrupted or continuous running

Choose the right spring-strength

b) Spring strength
 

Each unit is equipped with a medium-strength spring because this spring strength is required for the majority of uses. In addition, weak and strong springs are supplied with each carton unit so that they are available when needed.

In order to determine which spring is necessary at what temperatures, it is necessary to know what lubricant is being used. The correct spring can then be determined with the aid of the following list:
 

Spring
 

Operating temperature:Lubricant consistency class
01234
-23°C to +4°Cstrongmediumweak--
+5°C to +43°Cstrongmediummediumstrong-
+44°C to +93°C-weakmediummediumstrong
+94°C to +120°C--weakmediumstrong

Lubricant dispensers

c) Installation instructions
 
  • Check the spring used:
    Does the spring strength match to the selection table?
  • The lubricant dispenser is then screwed into the thread of the bearing.
    Prior to installation because no air cushions are then created between the bearing and the lubricant dispenser.
  • The lubricant dispenser is then screwed into the thread of the bearing.
    The dispenser's screw-in connector has an R 1/8" external thread. Appropriate adapter pieces may have to be fitted.
  • The lubricant dispenser can be installed in any position and operates interference-free, independently of its installation position.
    Line paths of more than 30 cm in length should be avoided.

 


Notes on lubricants

As a matter of principle, discussions about lubricants should not take place and should be prevented if at all possible, because the lubricant used by the customer will have been recommended by the lubricant manufacturer.

However, you need to know a few basic points because they are directly related to the function of the oil/grease cup. The most important characteristic of lubricants is their consistency. Only lubricants should be used whose individual constituents do not separate, i.e. the NLGI group, consistency class 0-4 (low base oil fraction). NLGI - the globally recognized group classification by the National Lubricating Grease Institute of America.
