Anyone have a decent place to buy casters.
looking for probably 4x2's for a welding table. Need 2 to have brakes, maybe all 4.
Looks like heavy duty casters run about $24 a piece on ebay, which is a bit more than I wanted to spend.
Harbor freight has some nice 5x1, and 5x2's for like $6 and $16 respectively, but neither of them have wheel brakes.
Also checked menards, and they dont' have any larger casters with brakes
It really depends on how heavy the load is and how much you need to move it.
In general I only design casters for 50% of load capacity when using high quality name brand castors. Meaning if you have four 500 lb rated casters I would only load them to 1000lbs max. If using Harbor Freight I would load them even less due to concerns of variation in quality.
As far as wheel material goes, I like Phenolic as it has high load capacity and it still easy to roll. A lot of the more eastomeric casters deform enough enough under high load that they are hard to move.
If the load is heavy and you need to move it more than once, I would recommend larger diameter caster wheel. It really makes a difference on easy of moving.
Wheel locks are a good idea, but consider access to the lock. I like Colson casters with the large lock coming out the back of the caster (see last photo). It is much easier to lock and unlock compared to side locking casters. But note I am not a fan of the the two piece (red/grey) caster wheel as shown below. I have seen too many of them fail under load due to age. The failure is the red "tire" comes off completely in red chunks when you attempt to move it.
Usually I use 2 fixed casters and two swivel casters with locks. Four swivel casters is a pain to push straight but can be useful in tight quarters if you have two people maneuvering it.
There can be deals on Ebay, but be very careful. Now that Ebay will let you protest not as expected condition shipments easier, you have some protection. But below are pictures of supposedly "as new" Colson casters I received on eBay. I suppose they were new before the flood.
