Made-to-measure products

Mechanical components

GrisGroup is an expert in the manufacture of complex mechanical components to close tolerances.

Thanks to the complementary nature of its processes (stamping, grinding, tooling, etc.), GrisGroup can support you in the study, design and production of all types of transmission components.

Shims

• Micron accuracy
• Wide dimensional range (Ø up to 200 mm)

Friction shims

• Flat or spherical shapes
• Controlled geometry and surface finish
• Textured surface for lubrication
• Optimised materials, treatments and coatings

Structural elements

• Planetary carrier for planetary gearbox
• Idler pinion support for hybrid gearbox
• Thrust ball bearing rail

Die-cut engineering parts

GrisGroup is able to supply all types of complex-shaped, technical metal parts in a wide range of dimensions, for the most diverse applications.

By combining processes, GrisGroup can produce the final shapes of parts without reworking: these parts, with their precise, finished functional surfaces, can be used directly: sizing, tapping, milling, counter-boring, chamfering, crimping studs, etc.

When complementarity and precision work in synergy, production aims for perfection!

TREP® exclusivity,

our catalogue product

GrisGroup is developing its expertise in the design of bolted assemblies. Our products guarantee perfect reliability and a homogeneous, high-performance combination of the various functions of the assemblies.

Guaranteed resistance to loosening, high resistance to unscrewing and suitability for all classes of screw quality make TREP® a unique and exclusive product, and one of which GrisGroup is proud.

• Guaranteed resistance to loosening
• Sustained tensioning of assembled elements
• Even distribution of bearing pressure

• High-stiffness, low-deformability elastic system
• Ability to accommodate thermal expansion
• Capacity to compensate and/or take up play (expansion, wear, etc.)

• Easy assembly thanks to crimping (handling of a single part instead of 3 or 4)
• No swaging of clamped parts
