Quality is our Pride, We don't take it lightly.
RHD's Quality Control Process
RHD has been producing quality bearings that meet the stringent demands of our customers. We produce both standard and tailor made custom solutions engineered for the toughest production challenges.
In these fast-moving times our combination of creativity, innovation and technical expertise ensures the customers' experience is consistent and through our best Quality Control processes we can guarantee industry leading quality in every bearing we manufacture.
The visual inspection is the start of our quality control checks. A trained eye can quickly determine any discrepancies or visual faults to the material or assembly.
RADIAL CLEARANCE TOLERANCE TESTING
The radial clearance is very important to the operation of the bearing. Our machines are calibrated regularly to ensure the tolerances adhere to DIN standards certificated by the German TUV.
INNER & OUTER TOLERANCE TESTING
The inner and outer tolerance test measures the precise dimensions of the bearing. Our strict tolerances are again set according to the DIN standards.
Highly sensitive microphones measure and identify audible peaks of a rotating bearing. These peaks can indicate faults to the raceways or possible grease pollution.
Using high, medium and low range frequencies, the vibration test can identify a range of bearing defects, such as imbalance, play and misalignment.
The Rockwell test determines the hardness of the material by measuring the depth of penetration of an indenter under load.
