Product Introduction

Bearing Fit Chart Shaft and Housing Pacamor Kubar Bearings

Miniature and instrument ball bearings are used in highprecision applications to mate parts control movement and provide rotational and oscillating functionality Aircraft medical instruments computers flow meters and pickandplace robots are just some of the challenging applications they are found in For example some highspeed

The design of every heavy duty bearing has been optimized to this end including our large bore bearings Years of experience have shown the need for a proper balance between rolling element diameter and raceway thickness Also considered is the length of the roller to its diameter and the thickness of any flanges on the races

Deep Groove Ball Bearings are one of the most widely used rolling bearings They are used to accommodate radial and axial loads in both directions With small friction and highlimit speed Ball Bearings are costeffective and require little maintenance

Typical Tolerances of Manufacturing Processes

processes and what their tolerance producing capability is After taking EML2322L the students should have a tangible understanding of the tolerances associated with basic manufacturing processes used in this course ie milling turning drilling reaming bandsaw cutting etc

the mill builder can provide the gear designer with input power and output speed The next step is the interface dimensions Since the gear needs to turn the mill it needs to have a bore larger than the mill outside diameter The mill outside diameter is a function
