- Standardised to ISO 3547 (DIN1494)
- Suit demands of wide range of applications
- Slim and compact design
- Inexpensive and fast availability
- Durable and maintenance-free materials available
- Sufficient lifespan to meet most repair intervals
HOWA CUSTOM DESIGN BEARINGS
At HOWA it is our aim to design the most practical, cost-effective and application-based-performing bearings. We always approach each project with an open mind, considering the experience from similar applications and yet thinking from scratch again.
All bearings from the Solid Machined Bearings range are produced-to-order. That offers full flexibility to achieve special geometrical shapes, sizes, tolerances, design features and anything else which make our bearings the most suitable for your application.
Applying our vast design experience, we develop custom-bearings for the most demanding and unique application requirements. Reach out to our Howa Team and get expert support.
Straight Bearing
The simple shape of a straight bush is the most commonly used bearing geometry, allowing the transfer of radial forces. Lubrication grooves and holes, cut-outs, etc. can be included with full flexibility.
Flanged Bearing
Next to radial forces, this bush design transfers axial forces via the flange face. The bush can be machined with mounting holes, lubrication channels, special dimensional tolerances and many other features.
Liners / Plates
Liner plates allow sliding motion in X and Y direction. They are available in round, oval, rectangular and square shapes featured with lubrication grooves, recessions and mounting features such as countersunk and tapped holes.
Half-Shell Bearings
A pair of Half-Shell Bushes is used when the assembly situation (or during future repairs) is unfavourable to the common axial assembly direction of the shaft. The shells are machined into perfect halves of each 180 degrees, ensuring full concentricity once installed into bore.
Spherical Plain Bearings
The matching spherical surfaces enable the bearing to self-align and balance-out misalignments of the adjacent structure. Our Spherical Plain Bearings follow the dimensions of DIN EN 12240-1 standard.
For all unique and highly demanding applications, we gladly go beyond this standard to create new design variations and develop the highest performing and the most cost-effective custom bearings.
Asymmetrical Spherical Plain Bearings
This design approach enables the spherical bearing to handle significantly higher axial forces than the standard radial bearing design. Its compact design minimises installation spaces and makes costly combinations of single Radial and Axial Bearings redundant.
Spherical Trunnion Bearings
This compact bearing design is meant to handle bi-directional radial – and axial forces occur. It can handle large misalignments through a flexible tilt angle setting. This bearing eliminates the need for complex bearing combinations and convinces with uncomplicated installation requirements.
Spherical Plates
Ideal for implementation in large steel structures where parallelism and dimensional accuracy are uncertain. The spherical surface accommodates omni-directional rotation and ensures even load distribution. The flat surface on the opposite site enables linear sliding motion to compensate expansion and contraction.
Typical applications are bridges, large roof and pipe structures and other heat generating installations that need underlay thermal contractions and expansions.
Special Shaped Bearings
Virtually any mechanically machinable shape can be transformed with our vast material selection into a sliding bearing. Single or multiple sliding surfaces, various bearing directions and anything else which seems impossible at first sight, is our speciality.
