## FAQs

**How do you calculate bearings?** Bearings are typically measured in degrees clockwise from north. To calculate the bearing between two points, you use trigonometry, specifically the arctangent function, with the differences in longitude and latitude of the two points.

**How do you calculate bearing selection?** Bearing selection depends on factors like load, speed, temperature, and environmental conditions. It involves considering these factors along with the type of bearing (e.g., ball, roller) suitable for the application.

**How do you calculate true bearing?** True bearing is the angle measured clockwise from true north. It’s calculated using trigonometry based on the differences in longitude and latitude between two points.

**How do I find bearings?** You can find bearings using a compass, GPS, or by calculating them using trigonometry with the coordinates of two points.

**What are the three rules of bearings?** The three rules of bearings are:

- Bearings are measured in degrees clockwise from north.
- Bearings are always three digits.
- Bearings can be measured as either true or magnetic bearings.

**How do you determine bearing size with dimensions?** Bearing size is determined based on factors like load, speed, shaft diameter, and housing dimensions. Manufacturers provide charts and calculations to match these parameters with the appropriate bearing size.

**How do you calculate bearing load capacity?** Bearing load capacity is determined by factors such as bearing type, size, material, lubrication, and operating conditions. Manufacturers provide load capacity charts based on these factors.

**How do you calculate end bearing capacity?** End bearing capacity depends on factors like soil type, depth, and diameter of the pile. It’s calculated using engineering formulas specific to soil mechanics and foundation design.

**What is the load bearing capacity of a bearing?** The load-bearing capacity of a bearing varies depending on its type, size, material, and operating conditions. It’s provided by the manufacturer and is typically specified in terms of radial and axial loads.

**How do you calculate forward and back bearings?** Forward and back bearings are calculated by adding or subtracting 180 degrees from the initial bearing depending on the direction of travel.

**Why are bearings 3 digits?** Bearings are three digits to ensure clarity and consistency in notation. This format helps avoid confusion and ensures bearings are interpreted correctly.

**What is an example of a true bearing?** An example of a true bearing might be “N 45° E,” indicating a direction 45 degrees east of true north.

**Are bearings always clockwise?** Yes, bearings are always measured clockwise from the reference direction, which is typically north.

**What is the 2 1 bearing rule?** The 2:1 bearing rule is used in navigation to estimate the course change needed to reach a destination. It means for every two degrees of bearing change, the distance traveled will change by approximately one nautical mile.

**Do bearings have to be whole numbers?** Yes, bearings are conventionally expressed as whole numbers to maintain clarity and consistency in navigation and engineering applications.

**How do you measure bearings with a protractor?** You can measure bearings with a protractor by aligning the base of the protractor with the north direction and then reading the angle clockwise from the north line.

**What size is a 6203 bearing?** A 6203 bearing typically has a bore diameter of 17 millimeters, an outer diameter of 40 millimeters, and a width of 12 millimeters.

**What is the most common bearing size?** The most common bearing size is 6203, which is widely used in various applications due to its versatility and availability.

**What do the letters on a bearing mean?** The letters on a bearing typically indicate the type of bearing, such as “RS” for rubber seals, “ZZ” for metal shields, and “C” for clearance.

**How do you calculate the outer diameter of a bearing?** The outer diameter of a bearing is calculated by adding twice the radial clearance to the inner diameter.

**What is the life of a bearing?** The life of a bearing is typically expressed in terms of the number of revolutions or operating hours before a certain percentage of bearings in a statistically significant sample will fail due to fatigue.

**How do you calculate pile size?** Pile size is calculated based on factors like soil type, load requirements, and structural considerations. Engineering calculations involving soil mechanics and foundation design are used to determine the appropriate pile size.

**How much load can a brick wall bear?** The load-bearing capacity of a brick wall depends on factors such as wall thickness, type of bricks, mortar quality, and foundation. Typically, a brick wall can bear several tons per square meter.

**What is a good bearing capacity?** A good bearing capacity depends on the specific application and load requirements. In general, higher bearing capacities are preferred for stability and safety.

**How do you find the load carrying capacity of a beam?** The load-carrying capacity of a beam is calculated using engineering formulas considering factors like beam material, cross-sectional shape, span, and loading conditions. Beam bending theory and structural analysis techniques are used for this calculation.
