Re: High Temperature Bearings - 8 years ago
I had read about that with bronze bushings especially. Igus offer more dirt resistant ones that i'll try first. If they don't work then I'll have to switch to a ceramic linear bearing like this: http://www.automotioncomponents.co.uk/en/catalog/linear/linear-ball-bushings/ceramic-linear-bearings/l1764. But as the sleeves are less than a quarter of the price i'll try those first.by Waka - Mechanics
Can someone mill my bearing housings (Aluminium/Steel)? - 8 years ago
Hi, I'm designing the powder spread for an SLS Printer and need some aluminium/steel block housings for my bearings. The bearing are these: Iglidur H1 Flange. Basically I'm looking for a block of Aluminium/Steel around 40mm x 20mm x 20mm. with a hole drilled for the bearings through the center of the block, one flange bearing will be fitted into each end of the block. Also 4 bolt holes drilleby Waka - Job Shop: I need stuff made!
Re: High Temperature Bearings - 8 years ago
Hi all, I've found some plain sleeve bearings I can use instead of ball bearings as they're a lot cheaper for the high temperature inside the heated chamber. has anyone had any experience with this kind of thing? http://www.igus.co.uk/iPro/iPro_02_0028_0000_GBen.htm?c=GB&l=en Thanksby Waka - Mechanics
Re: High Temperature Bearings - 8 years ago
Thanks for the reply. I have looked at ceramic bearings yes, but they also don't seem to come reasonably priced as linear bushings. The bearing I listed would be suitable if I can mount them but I'm hoping to find a standard part to avoid milling. I've managed to remove all other heat sensitive parts outside of the heated chamber but this is the last one in the design that has to be inside. I'mby Waka - Mechanics
High Temperature Bearings - 8 years ago
Hi, I've just joined the community after doing research for a little while and am designing an SLS printer at the moment. I'm going to be using a heated chamber and am designing the powder spreader. I'm thinking of using smooth rods and linear bushings, but am struggling to find them for reasonable prices that can withstand 180 Celsius. I've found a good price on high temperature ball bearings (by Waka - Mechanics
