We manufacture the flat cages according to the customer's requirements. We offer the following:
Our needle rollers are flat cages bent to a diameter according to customer requirements. Due to the cage guidance, higher speeds are possible compared to full complement bearings and these are suitable for pitch circle speeds up to n * d < 100,000 mm/min. They score with their low radial overall height and are also suitable for large shaft diameters. Our needle rollers can also be supplied in small quantities and are available at short notice. Due to an open butt joint, they can be easily mounted and oil and grease lubrication is possible. The radial needle roller and cage assemblies are units consisting of bent flat cages (IBFZ) fitted with needle rollers and can be supplied as complete bearing units including inner and outer steel rings (KR) as required. Without steel rings (K), a hardened and ground shaft and housing bore are required as raceway.
Radial flat cages are finding more and more areas of application - including in machine tools and gear manufacturing, where precision and high load ratings are required and proven materials are reaching the limits of their load capacity.
Steel flat cages can better support high loads under frequent alternating loads and high temperatures and allow significantly longer service lives under high stresses.
Small installation dimensions, flexibly producible dimensions, small purchase quantities, short-term availability and an attractive cost-benefit ratio are the main reasons why flat cages are frequently used.
Die Abdichtung erfolgt mit handelsüblichen Dichtungen zwischen Lager und Anschlußkonstruktion.
Flat cages, radial needle rollers and steel rings are corrosion protected and compact. Before start-up, depending on the lubrication method, the parts must be oiled or greased.
Radial needle rollers with steel rings are supplied ready for installation.
Flat cages are available in the following standard length units:
