Spherical ball, clearance-free, J4VEM, mm, igubal®

  • Dimensional series: E following DIN ISO 12240
  • Material of spherical ball: iglidur® J4V 
  • Pre-loaded clearance-free
  • Clearance-free in unloaded condition
  • Material spherical ball: iglidur® J4V
Product description
igubal® spherical ball J4VEM - clearance-free
 
Every single iglidur® material has its own special properties, which determine its suitability for specific applications and requirements.
The iglidur® J4 material features extremely low moisture absorption and is especially cost-effective. The special shape of the spherical ball pre-loads suitable shafts completely when they are in an unloaded state, ensuring that it is completely clearance-free.
 
Material properties
  • Low wear against a lot of shaft materials
  • Low coefficients of friction during dry operation
  • Vibration dampening
  • Good chemical resistance
  • Best material to use with soft shaft materials
  • Low moisture absorption

Typical application areas
  • Plant construction
  • Model making
  • Furniture/Industrial design
  • You will find plenty of additional application areas at our Industry solutions
 
When to use it?
  • If you need maintenance-free materials
  • When dimensional series E components are to be fitted
  • If high compressive strength is required
  • If high flexibility is required
When not to use it?
  • If temperatures are higher than +90 °C
  • If diameters above 20 mm are required
  • If rotation speeds higher than 0.5 m/s are required
Use our filter options to find the suitable product

Tolerances
 
Maintenance-free igubal® spherical balls are designed with a tolerance of the inner diameter of E10. The shaft tolerance should be between h6 and h9. Unless stated otherwise, all tolerance values are treated according to DIN ISO 2768-m
