NACHI 21309EXQW33C3 Spherical Roller Bearing With Cylindrical Bore, 45 mm Dia Bore, 100 mm OD, 2 Rows, 25 mm W, 150000 N Dynamic/124000 N Static Load
Double-rowed spherical roller bearings are the workhorse of the industry. Their barrel shaped rollers and spherical outer ring raceway permits this bearing to operate with misalignment with no reduction in bearing life. Spherical roller bearings are used mostly in heavy duty industrial applications where extreme radial loads exist. They also excel in handling axial loads in either direction, contaminated environments, misalignment, shock loads and vibration. Nachi Sphericals are manufactured in a number of design and material configurations depending upon the type of application and the size of the bearing. Most come standard with a lubrication groove and holes (W33) on the OD of the outer ring. Symmetrical or Asymmetrical (A) rollers may be used with stamped steel or machined brass cages. The "EX" design uses larger diameter rollers for the highest load ratings. All bearings are heat stabilized to at least 200 deg C (about 400 deg F). Some sizes may be available with tapered bores (K). Depending upon design, stamped steel or machined brass cages are used. Commonly used in gearboxes, wind turbines, pumps, mining/construction, marine propulsion and drilling equipment.

Southwire® Romex® SIMpull® 63947655 Type NM-B Non-Metallic Sheathed Cable With Ground Wire, Coil Packaging, 600 V AC, (3) 12 AWG Solid Copper Conductor, 250 ft L, Yellow
Southwire® Romex® Brand SIMpull ® NM-B (nonmetallic-sheathed) cable may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90C (with ampacity limited to that for 60C conductors) as specified in the National Electrical Code. NM-B cable is primarily used in residential wiring as branch circuits for outlets, switches, and other loads. NM-B cable may be run in air voids of masonry block or tile walls where such walls are not wet or damp locations. Voltage rating for NM-B cable is 600 volts.
Littelfuse® POWR-GARD® KLSR020 Current Limiting High Speed North American Style Fast Acting Fuse, 20 A, 600 V AC/250 V DC, 200/20 kA Interrupt, RK1 Class, Cartridge Body
KLSR series RK1 fuses were the earliest type of current limiting fuse developed. Their single element, silver link design enables them to provide fast acting overload and short circuit protection. When used to protect inductive loads such as motors, solenoids and transformers, KLSR series fuses must be greatly oversized to prevent opening the fuses on harmless inrush currents. In such applications, KLSR series fuses may only provide short circuit protection.
EATON BR225 Type BR Miniature Circuit Breaker, 120/240 V AC, 25 A, 10 kA Interrupt, 2 Poles, Thermal Magnetic Trip
Eaton’s BR circuit breakers are used in indoor and outdoor BR loadcenters, spa panels, meter breakers and sub panels. They are designed for a wide range of applications such as high short-circuit interrupt, series rating combinations with upstream main breakers, thermal magnetic, AFCI, GFCI, equipment protection and dual function AF/GF.
