Does anyone make a spherical bearing that can lock position to hold a shaft at angle to the centerline? I am trying to find one that would give me 30 or more degrees of angle from centerline.
Hi, it depends on your bearing requirement and the way it is in the machine, whatever......you could have a plumber block with a bearing that has a spherical mount so that the bearing will swivel in the block.
Some plumber blocks use self centreing ball bearings, but these are only really for slight shaft misalignment when mounted on non rigid framing structures.
The other type of plumber block uses regular radial bearings, but with the bearing outer race shell rounded on it's outer diam to allow it to swivel in the mount.
In both of these designs the inner race is longer than the bearing overall width, and some have grub screws to hold the assembly to the shaft, whilst others have a type of camlock ring that you rotate to hold the shaft and secure in position with a grub screw.
There are also types that have a tapered sleeve with a threaded collar that locks the bearing to the shaft etc.
If'n the machine requires a bearing in the machine body to allow the shaft to move through a 30 deg arc, you will need to have a purpose designed housing that is fitted to the machine.....self centreing bearings don't have the capacity to move though that much offset.
If'n the shaft is going to be permanently offset at 30 deg to the input or drive shaft, then a universal joint will be the answer, same as you have with a car's drive shaft from gearbox to the back axle, which allows radial movement in the shaft's end as it turns.
The universal joint will also fix the shaft rigidly in position to the drive shaft whilst allowing it to move radially as it turns.
A sketch of your layout would help.
