Ball Bearings, Bearing units, Linear Guides : industrial products on DirectIndustry

bearing The stationary support that accommodates a moving (normally rotating) shaft
linear guide The straight track, giving a smooth surface for a linear bearing
ball valve A valve, to control the flow of fluid in a pipe, that is opened or closed by turning a ball with a hole across its diameter (that allows fluid to flow when turned to be aligned with the pipe, and blocks it when turned to be perpendicular to the pipe)
ball bearing A low-friction system of balls, in a ball race, that is placed between a stationary support and the moving (normally rotating) shaft that it accommodates
grinding wheel A cylindrical disk, with an abrasive rim edge, fitted to a motorized tool that spins it at a fairly high speed
plain bearing A bearing that supports the load simply by sliding the two surfaces against each other
roller bearing A low-friction system of rollers that is placed between a stationary support and the moving (normally rotating) shaft that it accommodates
wheel loader A type of tractor with a wide square tilting bucket on the end of movable arms to lift and transport material
ball screw A mechanical device consisting of a threaded shaft that acts as a helical raceway for balls, thereby giving low friction, high accuracy, motion for the translating of rotational motion to linear motion via a screwing action
diamond grinding wheel
bearing unit A self-contained module, containing the bearings in place, for mounting between two moving surfaces (such as a rotating shaft on a chassis)
wheel excavator A mobile machine for digging out a hole (usually in the ground) mounted on wheels
spherical bearing A universal joint, able to bend in two dimensions, composed of two concentric rings, each one able to swivel orthogonally to the other
cut off wheel A circular cutting tool for cutting off the appropriate length from the original material
needle bearing A low-friction system of very thin rollers that is placed between a stationary support and the moving (normally rotating) shaft that it accommodates
linear bearing A type of bearing used where a component needs to be moved along a straight line with high accuracy
linear ball bearing A type of linear bearing with a straight ball raceway to smooth the motion
roller guide A system with a roller, two parallel rollers with a gap between them, or two such pairs of rollers arranged orthogonally, for guiding the material through the desired aperture
ball transfer unit
bearing puller A tool for removing axle bearings
precision bearing The stationary support that accommodates a moving (normally rotating) shaft, made to extremely fine tolerances
roller thrust bearing
thrust ball bearing A bearing composed of parallel washers that are separated by ball races, and that can transmit high axial loads but not radial loads
abrasive wheel
ball lens A double-convex lens in the shape of a small, almost spherical, ball
light guide A long tube of transparent material whose walls internally reflect any light attempting to exit, so that most of the light inserted at one end of the tube ends up exiting from the far end
miniature ball bearing
radial bearing A bearing facilitating rotation of a shaft within its support, while supporting a heavy load
ball mill A machine for grinding ores, chemicals, ceramics and paints. A set of stainless steel balls rotate around a horizontal axis, with the material entering at the top of the cylindrical housing, and shuffling down as the fine powder is removed from the bottom
ball screw actuator
flap wheel An abrasive or polishing wheel made up of flaps of flexible material
ball screw jack
ball joint A universal joint, able to bend in two dimensions, composed of a clasp on one connector that grips round the ball on the other connector
electronic ballast A resistor whose resistance increases as the current through it increases, thereby serving to stabilize the current at the original level
gear wheel A toothed wheel that engages in another, and made to turn so that the drive on one axle is coupled to the other axle
knurling wheel
miniature ball screw
radial ball bearing
ball check valve A non-return valve with a ball that presses against the seating at one end of the value, stopping the flow, in one direction, and leaves the ball free at the other end of the value, to allow the flow, in the other direction
ceramic bearing A bearing for a rotating shaft that is made of ceramic material
ceramic plain bearing
circuit board guide
flanged bearing A bearing, perhaps containing a ball race, whose outer housing has a flange for fixing it to the support
guide roller A wheel that is located perpendicular to the main supporting wheels, to guide the vehicle around a curve
miniature bearing The stationary support that accommodates a moving (normally rotating) shaft, of a small physical size
needle thrust bearing
plastic bearing The stationary support, made of plastic, that accommodates a moving (normally rotating) shaft
wheel motor
ball plunger A short cylindrical bolt with a head the same diameter as the body, as in a grub screw
bearing sensor
conveyor belt guide
drill bushing A bush or sleeve for supporting the free end of a drill bit
guide bushing
magnetic bearing A bearing that supports its load using magnetic levitation
taper bushing
ball stud
conical bearing
hydrodynamic bearing A bearing where the gap between the moving surfaces is small, and where the velocity is high enough to allow the viscosity of a film of oil to build up enough pressure hydrodynamically to keep the moving surfaces apart
microball cabinet
wheel scale
