MotorBike & Scooter appliances’ sector

Motorcycle & Scooter sector represents an important segment for motorized mobility with 2 or more wheels. Typical areas of interest are:

  • Standard assets: for daily use (urban mobility);
  • Sports assets: for competitive sports use (plains, hills, mountains);
  • Customizations for Professional Sports use (Track, Competition);
  • Hobby use and private maintenance.
Angular Contact, Angular displacement, Increased Load

Angular Contact, Angular displacement, Increased Load

Starting from Standard solutions for Radial Load (0° DEG) and Angular Contact (15°, 25°, 30°, 40° DEG), Customized versions are available, in order to choose the Angular Displacement’s maximum excursion. Same concept is also applicable referring to admissible loads.

Mounting Requirements

Mounting Requirements

Often P0 tolerances (Standard) are not enough to meet a specific assembly needs. Also in this case it is possible to verify these requirements and have customized solutions, able to make available both the production process and maintenance operations.

Materials, Lubrication and Temperatures

Materials, Lubrication and Temperatures

Materials resistance related to operating conditions is certainly an important aspect, infact the bearing life depends on this, in terms of effective performed life. In this sense, many technical solutions are available (both Standard and Custom) able to meet the specific use.

Key features

Key features

1. Analysis & Technical Feasibility, in order to pass the Homologation Test on Final Customer Appliance;
2. Documentations & PPAP, Automotive level;
3. Coupling tollerances and Clearances, designed to meet mounting exigences;
4. Super pure 100Cr6 steels to increase the bearing life;
5. Plastic or Steel Cages, to Gabbie in Plastica to support the best behavior of the rolling elements;
